Judges 11:16, 18

For when they came up from Egypt, Israel walked through the wilderness to the Red Sea and came to 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.
