211 When the Canaanite, the king of Arad, who dwelt in the Negeb, heard that Israel was coming by the way of Atharim, he fought against Israel, and took some of them captive. 2 And Israel vowed a vow to the Lord, and said, "If thou wilt indeed give this people into my hand, then I will utterly destroy their cities." 3 And the Lord hearkened to the voice of Israel, and gave over the Canaanites; and they utterly destroyed them and their cities; so the name of the place was called Hormah.

(Read Numbers 21:1-3)
Before the people began their march round the country of Edom, the king of Arad, a Canaanite, who inhabited the southern part of the country, attacked them in the wilderness, and took some prisoners. This was to lead the Israelites to look more thoroughly to the Lord.
