John Gill 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
To the place of slaughter; who shall be able to make no more resistance than lambs. This explains what is meant by being made drunk, and sleeping a perpetual sleep, even destruction and death: like rams with he goats ;
denoting the promiscuous destruction of the prince and common people together.
