Numbers 21:30

27 Therefore those who speak in proverbs say, Come you to Heshbon; Let the city of Sihon be built and established:

28 For a fire is gone out of Heshbon, A flame from the city of Sihon: It has devoured Ar of Moab, The lords of the high places of the Arnon.

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

30 We have shot at them; Heshbon is perished even to Dibon, We have laid waste even to Nophah, Which [reaches] to Medeba.

31 Thus Israel lived in the land of the Amorites.

32 Moses sent to spy out Jazer; and they took the towns of it, and drove out the Amorites who were there.

33 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 battle at Edrei.
