Numbers 21:29-33

Woe to thee, Moab! thou art undone, O people of Chemosh: he hath given his sons that escaped, and his daughters, into captivity unto Sihon king of the Amorites.

We have shot at them; Heshbon is perished even unto Dibon, and we have laid them waste even unto Nophah, which reacheth unto Medeba.

Thus Israel dwelt in the land of the Amorites.

And Moses sent to spy out Jaazer, and they took the villages thereof, and drove out the Amorites that were there.

And they turned and went up by the way of Bashan: and Og the king of Bashan went out against them, he, and all his people, to the battle at Edrei.
