Deuteronomy 2:30-33

30“But Sihon king of Heshbon would not let us pass through, for the Lord your God hardened his spirit and made his heart obstinate, that He might deliver him into your hand, as it is this day.

31“And the Lord said to me, ‘See, I have begun to give Sihon and his land over to you. Begin to possess it, that you may inherit his land.’

32Then Sihon and all his people came out against us to fight at Jahaz.

33And the Lord our God delivered him over to us; so we defeated him, his sons, and all his people.
