Victory at Hormah
21:1 When the Canaanite king of Arad who lived in the Negev heard that Israel was approaching along the road to Atharim, he fought against Israel and took some of them prisoner.
Numbers 21:22-24
21:22 “Let us pass through your land; we will not turn aside into the fields or into the vineyards, nor will we drink water from any well, but we will go along the King’s Highway until we pass your borders.”
21:23 But Sihon did not permit Israel to pass through his border; he gathered all his forces together and went out against Israel into the wilderness. When he came to Jahaz, he fought against Israel.
21:24 But the Israelites defeated him in battle and took possession of his land from the Arnon to the Jabbok, as far as the Ammonites, for the border of the Ammonites was strongly defended.
