Or HaChaim on Exodus 3:22/אור החיים על שמות ג׳:כ״ב

1 ונצלתם את מצרים, "you will empty Egypt." Here the Torah alludes to the fact that a person may rescue his possessions from someone who robbed him by force. Alternatively, our verse may be a preview of what caused the Egyptians to drown in the sea, i.e. the combination of the Israelites' demand to borrow their silver trinkets and their declared intention to travel a distance of three days into the desert. The two demands eventually prompted the Egyptians to pursue the Jews believing their leader Moses had overstepped his authority. As a result G'd drowned them in the sea.
