Here the increase in Yahweh's anger is spoken of as if it were a growing fire. Alternate translation: "Yahweh's anger grew like a fire against Amaziah" (See: [[rc://en/ta/man/translate/figs-metaphor]])
The prophet uses this rhetorical question to rebuke Amaziah for worshiping the powerless gods of the people he had defeated. Here the word "hand" is a metonym for power. The question can be translated as a statement. Alternate translation: "You have worshiped the gods of a people that did not even save their own people from your power, King Amaziah."
