Moses used this question to try to persuade God not to destroy his people. This rhetorical question can be translated with a statement. Alternate translation: If you destroy your people, the Egyptians might say, 'He led them out ... to destroy them from the face of the earth.' (See: [[rc://en/ta/man/translate/figs-rquestion]])
Moses speaks of God's anger as if it were a fire that was burning. Alternate translation: "your terrible anger" (See: [[rc://en/ta/man/translate/figs-metaphor]])
