God's anger is spoken of as something that covered over Judah and Jerusalem. Here the words "Judah" and "Jerusalem" are metonyms for the people who lived there. Alternate translation: "God became very angry with the people of Judah and Jerusalem" (See: [[rc://en/ta/man/jit/figs-metaphor]] and [[rc://en/ta/man/jit/figs-metonymy]])
