Numbers 21:29

26 For Heshbon was the city of Sihon the king of the Amorites, who had fought against the former king of Moab, and taken all his land out of his hand, even to the Arnon.

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.
