Deuteronomy 2:24-27

‘Now arise, continue on, and go through the valley of the Arnon. Look, I have handed over to you Sihon the Amorite, king of Heshbon, and his land. Begin! Take possession [of it] and fight with him in battle. This day I will begin to put the dread and the fear of you on the peoples (pagans) under the whole heaven, who, when they hear the reports about you, will tremble and be in anguish because of you.’ “So I sent messengers from the Wilderness of Kedemoth to Sihon king of Heshbon with words of peace, saying, ‘Let me pass through your land [with my people]. I will travel [with them] only on the highway; I will not turn away to the right or to the left.
