David's writing gloriously and miraculously transcends his experience as we listen to the epic themes of redemption soaring above temporal constraints in music composed first in heaven and echoed through the lyrics of Israel's typological king. The author of Hebrews recognized the prophetic weight of Ps 40 in Heb 10. This New Testament confirmation of messianic foreknowledge is striking in its timelessness. Long before John the Baptist identified Christ in the flesh, David had identified Him in song announcing as though returning from time travel into the future... “Behold the Lamb of God”. Let us behold the Lamb in this ancient hymn today!
