21 And Israel sent messengers to Sihon king of the Amorites, saying, 22 Let me pass through your land. We will not turn aside into field or vineyard; we will not drink the water of the wells. We will go by the king's highway until we have passed your border. 23 But Sihon would not allow Israel to pass through his border. Instead Sihon gathered all his people together and went out against Israel into the wilderness, and came to Jahaz, and he fought against Israel. 24 And Israel smote the king of the Amorites with the edge of the sword and possessed his land from the river Arnon to the river Jabbok, as far as the Ammonites, for the boundary of the Ammonites was strong. 25 And Israel took all these cities and dwelt in all the cities of the Amorites, in Heshbon and in all its towns. 26 For Heshbon was the city of Sihon king of the Amorites, who had fought against the former king of Moab and taken all his land out of his hand, as far as [the river] Arnon.
27 That is why those who sing ballads say, Come to Heshbon, let the city of Sihon be built and established. 28 For fire has gone out of Heshbon, a flame from the city of Sihon; it has devoured Ar of Moab and the lords of the heights of the Arnon. 29 Woe to you, Moab! You are undone, O people of [the god] Chemosh! Moab has given his sons as fugitives and his daughters into captivity to Sihon king of the Amorites. 30 We have shot them down; Heshbon has perished as far as Dibon, and we have laid them waste as far as Nophah, which reaches to Medeba.
