Psalm 135 publishes a command to worship Yahweh and chronicles occasions for worship from nature, history, and covenant. Echoing themes from Ps 134, Ps 135 opens reprising a call to worship extending firstly to those with priestly duties commissioned to serve the Lord in His house (temple). The song continues by recounting & extolling works of the Lord and condemning the foolishness of idolatry. Finally Psalm 135 closes with another call to worship chorus this time broadcasting across the world that all the people of God might join him in song. Note: portions of this song might sound familiar. Verses 15-21 are a nearly word-for-word parallel with Ps 115:4-13 reminding us that the church has gathered together to repeat songs of worship for millennia from the days of leather scrolls to our own assembly here today.
