then Israel sent messengers to the king of Edom, saying, “Please let us pass through your land,” but the king of Edom would not listen. Also they sent word to the king of Moab, but he would not consent. So Israel stayed at Kadesh.

Then they went through the wilderness and went around the land of Edom and the land of Moab, and came to the east side of the land of Moab, and they camped on the other side of the [river] Arnon; but they did not enter the territory of Moab, for the Arnon was the [northern] boundary of Moab.
