Deuteronomy 2:24-25

2:24 Get up, make your way across Wadi Arnon. Look! I have already delivered over to you Sihon the Amorite, king of Heshbon, and his land. Go ahead! Take it! Engage him in war! 2:25 This very day I will begin to fill all the people of the earth with dread and to terrify them when they hear about you. They will shiver and shake in anticipation of your approach.”
