Deuteronomy 2:24-25

24“Arise, set out, and cross the Arnon Valley. See, I have delivered into your hand Sihon the Amorite, king of Heshbon, and his land. Begin to take possession of it and engage him in battle. 25This very day I will begin to put the dread and fear of you upon all the nations under heaven. They will hear the reports of you and tremble in anguish because of you.”
