Charles Ellicott Commentary Jeremiah 50:29

"Call together the archers against Babylon, all them that bend the bow; encamp against her round about; let none thereof escape: recompense her according to her work; according to all that she hath done, do unto her; for she hath been proud against Jehovah, against the Holy One of Israel." — Jeremiah 50:29 (ASV)

Recompense her according to her work ... —As before, in Jeremiah 50:15, the prophet sees in the fall of Babylon the working of the Divine law of retribution. In “the Holy One of Israel” we note the occurrence, for the first time in Jeremiah, of the characteristic name which is so prominent in Isaiah, and is seldom found elsewhere. It occurs again in Jeremiah 51:5.
