Judges 11:17-18

11:17 Then Israel sent messengers unto the king of Edom, saying, Let me, I pray thee, pass through thy land: but the king of Edom would not hearken [thereto]. And in like manner they sent unto the king of Moab: but he would not [consent]: and Israel abode in Kadesh. 11:18 Then they went along through the wilderness, and compassed the land of Edom, and the land of Moab, and came by the east side of the land of Moab, and pitched on the other side of Arnon, but came not within the border of Moab: for Arnon [was] the border of Moab.
