Joshua 15:13-17

Now he gave to Caleb the son of Jephunneh a portion among the sons of Judah, in accordance with the command of the Lord to Joshua, namely, Kiriath-arba, Arba being the father of Anak (that is, Hebron).

And Caleb drove out from there the three sons of Anak: Sheshai, Ahiman, and Talmai, the children of Anak.

Then he went up from there against the inhabitants of Debir; now the name of Debir previously was Kiriath-sepher.

And Caleb said, “The one who attacks Kiriath-sepher and captures it, I will give him Achsah my daughter as a wife.”

Othniel the son of Kenaz, the brother of Caleb, captured it; so he gave him Achsah his daughter as a wife.
