Deuteronomy 2:30

27 Let me go through your land: I will keep to the highway, not turning to the right or to the left;

28 Let me have food, at a price, for my needs, and water for drinking: only let me go through on foot;

29 As the children of Esau did for me in Seir and the Moabites in Ar; till I have gone over Jordan into the land which the Lord our God is giving us.

30 But Sihon, king of Heshbon, would not let us go through; for the Lord your God made his spirit hard and his heart strong, so that he might give him up into your hands as at this day.

31 And the Lord said to me, See, from now on I have given Sihon and his land into your hands: go forward now to take his land and make it yours.

32 Then Sihon came out against us with all his people, to make an attack on us at Jahaz.

33 And the Lord our God gave him into our hands; and we overcame him and his sons and all his people.
