Deuteronomy 2:26-32

26And I sent messengers from the wilderness of Kedemoth to Sihon king of Heshbon with words of peace, saying, 27Let me pass through thy land: I will go along by the highway, I will neither turn to the right hand nor to the left. 28Thou shalt sell me food for money, that I may eat; and give me water for money, that I may drink: only I will pass through on my feet; 29(As the children of Esau who dwell in Seir, and the Moabites who dwell in Ar, did to me;) until I shall pass over Jordan into the land which the LORD our God giveth us. 30But Sihon king of Heshbon would not let us pass by him: for the LORD thy God hardened his spirit, and made his heart obstinate, that he might deliver him into thy hand, as appeareth this day. 31And the LORD said to me, Behold, I have begun to give Sihon and his land before thee: begin to possess, that thou mayest inherit his land. 32Then Sihon came out against us, he and all his people, to fight at Jahaz.
