“Matthew 21:42
Jesus saith unto them, Did ye never read in the scriptures, The stone which the builders rejected, the same is become the head of the corner: this is the Lord’s doing, and it is marvellous in our eyes?
Jesus saith unto them, did ye never read the Scriptures,…. The passage which stands in Psalm 118:22.
The stone which the builders rejected, the same is become the head of the corner: this is the Lord’s doing, and it is marvellous in our eyes. Very appropriately is this Scripture cited, and applied to the present case; which expresses the rejection of the Messiah by the Jewish builders, priests, and scribes: the whole Psalm may be understood of the Messiah. R. David Kimchi owns (z), that there is a division among their Rabbins about it: some say that the Psalm is spoken of David, and others, that it is spoken of the days of the Messiah; and these are certainly in the right; and as for this particular passage, it is applied by some of them to the Messiah: so on mentioning Hosea 3:5 they (a) say,

“David was king in this world, and David shall be king in the time to come: wherefore it is said, the stone which the builders refused, &c.

And one of their noted commentators (b) on those words, “though thou be little among the thousands of Judah”, has this note:

“It is fit thou shouldest be little among the families of Judah, because of the impurity of Ruth the Moabitess, which is in thee: out of thee shall come forth unto me, Messiah, the son of David; for so he saith, “the stone which the builders refused”, &c.

Christ is often in Scripture compared to a stone, and is called the stone of Israel; is said to be a stone of stumbling to some, and a precious tried stone to others: is represented as a stone cut out of the mountain without hands, and on which are seven eyes: and is fitly compared to one, for his usefulness in the spiritual building the church, where he is as both the foundation and corner stone, and for his strength and duration. Christ is the sure, firm, and everlasting foundation, which God has laid in Zion, and the only one of any avail; nor can any other be laid to any purpose; and if he is neglected, and laid aside, in the ministration of the word, the building which men endeavour to rear, or exhort unto, will come to nothing. Whoever build on him are safe, and on nothing else: Christ is the foundation, on which the church, and every believer, are built, and therefore will abide; for the gates of hell cannot prevail against them: the covenant of grace is immoveable, being established in him; its mercies are sure, and its promises yea and amen: the salvation of immortal souls is certain, resting upon him; the faith and hope of the saints fail not, being directed to, and settled on him: the house not made with hands, which is in heaven, is an eternal one; and the city, which has foundations, is a continuing one, because of the concern that Christ has in it; and though he is of such eminent use and importance in the building, yet, as such, the “builders rejected” him: by the builders are meant, the Jewish rulers, both political and ecclesiastical, especially the latter, who pretended to instruct, and build up the people in knowledge and understanding; but in a very bad way did they do it, and upon a very sandy foundation, upon their fleshly privileges, their moral righteousness, and the observance of the ceremonial law, and the traditions of the elders. The Jews used to call their doctors and their scholars “builders” (c): says R. Jochanan,

“the disciples of the wise men are called “builders”, because they study in the building of the world all their days, which is the law.

These rejected the Messiah, refused to receive, and acknowledge him as such: they disallowed and disapproved of him, as base and vile, and the most contemptible of mortals, and set him at nought, and had him in the utmost scorn and derision. And so he is rejected by some who bear the characters of builders among Christians: as when his proper deity, and eternal sonship are denied, and he is treated as a mere creature; when his satisfaction and atoning sacrifice are either wholly rejected, or little regarded, lessened, and depreciated, and repentance and good works are put in the room of them; when his imputed righteousness is opposed, and laid aside, and the righteousness of men preferred unto it, and cried up as the matter of justification in the sight of God; when his efficacious grace is represented as unnecessary to regeneration, conversion, and sanctification, and to the performance of good works; and when he is left out of public ministrations, as the way of life and salvation, as the fountain of all grace, and foundation of all happiness, and human power, free will, and moral righteousness are put in his room. But notwithstanding the former and present rejection, and ill treatment of him, he is

become the head of the corner: he is the corner stone in the building which knits and cements it together, angels and men, Jews and Gentiles; Old and New Testament saints; saints above, and saints below, and in all ages and places, all meet, and are united together in this corner stone; which also strengthens and supports the building, and holds it together, and is the ornament and beauty of it: he is the chief corner stone; he is higher than the kings of the earth; he is superior to angels, and the chiefest among ten thousands of his saints; he is exalted above all creatures, angels, and men, who, by the Jewish builders, was despised and rejected, and scarce allowed to be worthy the name of a man:

this is the Lord’s doing; this stone is laid in the building by him: the rejection of him is according to his determinate counsel and foreknowledge; and the exaltation of him, above every name, is owing to him, and he is by, and at his own right hand: and

is marvellous in our eyes; in the eyes of all the saints; there being in all this such, a wonderful display of the wisdom, grace, mercy, power, and faithfulness of God,

Matthew 21:43
Therefore say I unto you, The kingdom of God shall be taken from you, and given to a nation bringing forth the fruits thereof.
Therefore I say unto you,…. This is the application of the parable; and the words are directed to the chief priests, elders, scribes, and people of the Jews; and are delivered as what would be in consequence of the builders, rejecting the Messiah, the foundation and corner stone of the building,
The kingdom of God shall be taken from you: by which is meant, not their political estate, their civil government, which was of God, and in a short time was to depart from them, according to ancient prophecy, and which is come to pass, as the event shows; nor their legal national church state and ordinances only, or the priesthood, and the appendages of it; all which, in a little while, were shaken and removed; but the Gospel, which had been preached among them by John the Baptist, Christ, and his apostles; so called because it treats of the kingdom of God, and things pertaining to it, and shows men both their right and meetness for it; the one as in the righteousness of Christ, and the other in the regenerating and sanctifying grace of the Spirit, which Gospel may be taken away from a people, as from the Jews, because of their contempt of it, and opposition to it, or lukewarmness and indifference about it, or unfruitfulness under it; and when God has no more souls to gather in by it in such a place, and which is a very unhappy case, whenever it is the case of any people: for when the Gospel is taken away, the riches of a people are gone; the glory of a nation is departed; the light of it is put out; the spiritual bread of a people is no more; the means of conversion and spiritual knowledge cease: all which have a melancholy aspect on posterity. Moreover, the Gospel church state, which was set up in Judea, may be here meant; which, though it continued and flourished a while, in process of time was to be removed: and which may be done elsewhere, as it has been in Judea, by God’s suffering persecution to arise, as he did against the church of Jerusalem, whereby the ministers of the Gospel are driven into corners, or scattered abroad; or by ordering his ministers to preach no more unto such a people, as the apostles were ordered to turn from the Jews to the Gentiles; or by taking away ministers and members of churches by death, and not raising up others in their room; or by withholding a blessing from the word; or by permitting the growth of errors and heresies, which, in course of time, must issue in the dissolution of the church state in such a place, and which necessarily follows upon the removing of the Gospel:

and given to a nation bringing forth the fruits thereof. Though God may take away the Gospel from a people, as he did from the Jews; yet he does not, nor will he, as yet, take it out of the world: he gives it to another “nation”; to the Gentiles, to all the nations of the world, whither he sent his apostles to preach and where it must be preached before the end of the world comes, in order to gather his elect out of them: for not one particular nation is meant, unless the nation of God’s elect, among all nations, can be thought to be designed. It may be observed, that the Gospel, wherever it comes, it comes as a gift; it is “given”: to have it only in the external ministration of it, is a favour; and more especially to understand it spiritually; this is an unmerited gift; as is also ability to preach it: and it is likewise a national mercy wherever it comes; for though it comes in power only to a few in a nation, yet it is more or less a blessing to the whole: nor is it easy to say what temporal advantages a nation enjoys through the ministration of the Gospel in it: and where it is given, and comes in power, it brings forth fruit, as it did in all the world of the Gentiles; even the fruits of grace, and righteousness, and every good work; all which come from Christ, under the influence of his Spirit, and by the word and ordinances, as means, and highly become the Gospel, and the professors of it; and for want of which it is removed sometimes from one nation to another: for this cause it was taken from the Jews, and given to the Gentiles. One of the Jewish commentators (d) on these words, in Jeremiah 13:17 “my soul shall weep in secret places for your pride”, has this note,

“because of your grandeur, which shall cease; because of the excellency of “the kingdom of heaven”, , “which shall be given to the profane”;

i.e. the nations of the world,

(d) Jarchi in Jeremiah 13.17.

Matthew 21:44
And whosoever shall fall on this stone shall be broken: but on whomsoever it shall fall, it will grind him to powder.
And whosoever shall fall on this stone,…. This is not to be understood of believing in Christ, or of a soul’s casting itself on Christ, the foundation stone; relying on him, and building all its hopes of happiness and salvation on him; which is attended with contrition and brokenness of heart, or repentance unto life, which needed not to be repented of nor of a believer’s offending Christ by evil works, whereby his conscience is wounded, his soul is grieved, and his faith shaken; and though he is hereby in great danger, he shall not be utterly destroyed, but being recovered by repentance, shall be preserved unto salvation; but of such to whom Christ is a stone of stumbling, and a rock of offence: for as he is the foundation and corner stone to some, and is set for the rising of them, and to whom he is precious; so he is a stone set for the fall of others, and at which they stumble and fall, and fall upon it: and such are they who are offended at Christ’s state of humiliation on earth; at the manner of his birth, the meanness of his parentage, and education; the despicable figure he made in his person, disciples, and audience; and at his sufferings and death: and these “shall be broken”: as a man that stumbles at a stone, and falls upon it, breaks his head or his bones, at least bruises himself, does not hurt the stone, but the stone hurts him; so all such as are offended at Christ, injure their own souls, being filled with prejudices against him, and contempt and disbelief of him, which if grace prevents not will issue in their everlasting destruction: but whilst there is life, the means of grace continue, the kingdom of God is not taken away; there is hope that such may be recovered from their impenitence and unbelief: “but on whomsoever it shall fall, it will grind him to powder”. Just as if a millstone, or any stone of such like weight and bulk, was to fall upon an earthen vessel; or, as the stone cut out of the mountain without hands, by which the Messiah and his kingdom, are designed, brake in pieces the image in Nebuchadnezzar’s dream, so that it became like the chaff of the summer threshing floor. As the former part of this verse expresses the sin of unbelievers, and the danger they are exposed unto by it, this sets forth their punishment; and has respect both to the vengeance of Christ, on the Jewish nation, at their destruction, which would fall heavy from him in his state of exaltation, for their evil treatment of him in his state of humiliation; and to his severe wrath, which will be executed at the day of judgment on all unbelievers, impenitent Christless sinners, who have both offended him, and been offended at him; when their destruction will be inevitable, their salvation irretrievable, and their souls irrecoverably lost, and ruined. Some have thought, that there is an allusion in these words to the manner of stoning among the Jews, which was this (e):
“the place of stoning was two men’s heights; one of the witnesses struck him on his loins, to throw him down from thence, to the ground: if he died, it was well; if not, they took a stone, which lay there, and was as much as two men could carry, and cast it, with all their might, upon his breast: if he died, it was well; if not, he was stoned by all Israel.

Maimonides observes (f), that “stoning, or throwing down from the high place, was that he might fall upon the stone, or that the stone might fall upon him; and which of them either it was, the pain was the same.

Matthew 21:45
And when the chief priests and Pharisees had heard his parables, they perceived that he spake of them.
And when the chief priests and Pharisees,…. Which latter, though not before mentioned, were many of them of the grand sanhedrim, as well as the chief priests, scribes, and elders: “had heard his parables”; that of the two sons being sent into the vineyard, and that of the letting out the vineyard to husbandmen,
they perceived that he spake of them: they plainly saw that they were designed by the son, that promised to go into the vineyard, but did not; only talked of works, but did not do them: and that they were the husbandmen that acted the ungrateful part to the householder, and the cruel one to his servants, and would to his son, their own consciences told them they were the men. They knew that the whole was levelled against them, and designed for them, and exactly hit their case.”
