Charles Ellicott Commentary Psalms 76:6

"At thy rebuke, O God of Jacob, Both chariot and horse are cast into a deep sleep." — Psalms 76:6 (ASV)

Are cast into a deep sleep. —The same Hebrew expression is used of Sisera’s profound slumber (Judges 4:21). Deborah’s Song and Exodus 15 are in the poet’s mind, as they were to the author of Isaiah 43:17, and as they have inspired the well-known lines of Byron’s “Sennacherib.”
