Numbers 21:31

29Woe to you, Moab! You are undone, people of Chemosh! He has given his sons as fugitives, and his daughters into captivity, to Sihon king of the Amorites.

30We have shot at them. Heshbon has perished even to Dibon. We have laid waste even to Nophah, Which reaches to Medeba.”

31Thus Israel lived in the land of the Amorites.

32Moses sent to spy out Jazer. They took its villages, and drove out the Amorites who were there.

33They turned and went up by the way of Bashan. Og the king of Bashan went out against them, he and all his people, to battle at Edrei.
