Moses speaks a poetic song to the people of Israel. Moses continues to use parallelism to emphasize what he is saying. (See: rc://en/ta/man/translate/figs-parallelism)

Vengeance is mine to give, and recompense

The words "vengeance" and "recompense" mean basically the same thing. AT: "I will have vengeance and punish Israel's enemies" (See: rc://en/ta/man/translate/figs-doublet)

at the time when their foot slips

This means God will eventually destroy their enemy. AT: "when the time is right for them to fall" or "when the time comes for me to destroy them"

and the things that are to come on them will hurry to happen

AT: "and their doom will come quickly"
