13 The Lord commanded Joshua to assign some of Judah's territory to Caleb son of Jephunneh. So Caleb was given the town of Kiriath-arba (that is, Hebron), which had been named after Anak's ancestor. 14 Caleb drove out the three groups of Anakites-the descendants of Sheshai, Ahiman, and Talmai, the sons of Anak.

Commentary on Joshua 15:13-19
(Read Joshua 15:13-19)
Achsah obtained some land by Caleb's free grant. He gave her a south land. Land indeed, but a south land, dry and apt to be parched. She obtained more, on her request, and he gave the upper and the nether springs. Those who understand it but of one field, watered both with the rain of heaven, and the springs that issued out of the earth, countenance the allusion commonly made to this, when we pray for spiritual and heavenly blessings which relate to our souls, as blessings of the upper springs, and those which relate to the body and the life that now is, as blessings of the nether springs. All the blessings, both of the upper and the nether springs, belong to the children of God. As related to Christ, they have them freely given of the Father, for the lot of their inheritance.
