Deuteronomy 2:24-25

24Rise up, take your journey, and pass over the river Arnon. Behold, I have given into thy hand Sihon the king of Heshbon, the Amorite, and his land: begin, take possession, and engage with him in battle.

25This day will I begin to put the dread of thee and the fear of thee upon the peoples under the whole heaven; who will hear report of thee, and will tremble, and quake because of thee.
