Yahweh's wrath is spoken of as if it were alive and could act on its own. Alternate translation: "Yahweh will not stop being angry until he" (See: [[rc://en/ta/man/jit/figs-personification]])
Here "heart's intentions" refers to the things that Yahweh wanted to happen. Alternate translation: "completed and accomplished all the punishment that he had planned" (See: [[rc://en/ta/man/jit/figs-metonymy]])
