God speaks of causing the enemies to steal their horses as if he carried the horses away. Alternate translation: "I made your enemies take away your horses" (See: [[rc://en/ta/man/translate/figs-metonymy]])
A stench is a bad smell. The stench coming up to their nostrils represents them smelling something terrible. It can be stated clearly that the smell was from the dead bodies of those who were killed. Alternate translation: "I made you smell the terrible odor of the dead bodies in your camp" (See: [[rc://en/ta/man/translate/figs-metonymy]] and [[rc://en/ta/man/translate/figs-explicit]])
