3 The Lord heard the Israelites' request and gave them victory over the Canaanites. The Israelites completely destroyed them and their towns, and the place has been called Hormah ever since.

Matthew Henry's Commentary on Numbers 21:3

Commentary on Numbers 21:1-3

(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.
