Jeremiah 21:5-6

The Lord promised that not only the Babylonians but He, too, would fight against the city. He would bring His strong arm against Jerusalem in anger and would strike down its inhabitants (cf. Deuteronomy 4:34; et al.). Normally the Divine Warrior fought for His people, but now He would fight against them. Humans and animals would die from the sword and from diseases, a curse for breaking covenant (cf. Jeremiah 14:12; Jeremiah 32:24; Exodus 5:3; Exodus 9:15; Numbers 14:12).
