Charles Ellicott Commentary Jeremiah 51:40

"I will bring them down like lambs to the slaughter, like rams with he-goats." — Jeremiah 51:40 (ASV)

I will bring them down like lambs to the slaughter ... —The figure is changed, and the revellers appear as themselves destined to be the victims of the slaughter-house (Jeremiah 48:15; Jeremiah 50:27). As the “bullocks” of Jeremiah 50:27 are the chosen warriors, so the lambs, sheep, he-goats represent the different classes of the population of Babylon (Isaiah 34:6; Ezekiel 39:18). All alike are given over to the sword.
