Deuteronomy 2:29-31

New Catholic Bible

²⁹ This is what the descendants of Esau who live in Seir and the Moabites who live in Ar did for me. Then I will pass over the Jordan into the land that the Lord, our God, has given us.” ³⁰ But Sihon, the king of Heshbon, would not let us pass through, for the Lord had hardened his spirit and made his heart stubborn so that he might deliver him into your hands, as he has today.

³¹ Then the Lord said to me, “I have begun to deliver Sihon and his land to you. Now begin to take it, so that you may inherit his land.”
