15 Then he went up from there to the inhabitants of Debir (formerly the name of Debir was Kirjath Sepher). 16 And Caleb said, "He who attacks Kirjath Sepher and takes it, to him I will give Achsah my daughter as wife." 17 So Othniel the son of Kenaz, the brother of Caleb, took it; and he gave him Achsah his daughter as wife. 18 Now it was so, when she came to him, that she persuaded him to ask her father for a field. So she dismounted from her donkey, and Caleb said to her, "What do you wish?" 19 She answered, "Give me a blessing; since you have given me land in the South, give me also springs of water." So he gave her the upper springs and the lower springs.

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.
