Exodus 15:16

Fear and dread shall fall upon them. — A portion of the Edomites felt so much fear of Israel that they allowed them to pass through their coasts (Deuteronomy 2:4). The Moabites of Aracted similarly (Deuteronomy 2:29).

Till thy people pass over — i.e., cross the frontier of the Canaanites, and enter their country. There is no need to suppose that Moses had as yet any distinct idea of the place where the frontier would be crossed.
