Joshua 15:15-17

And he went up from there against the inhabitants of Debir. Now the name of Debir formerly was Kiriath-sepher. And Caleb said, “Whoever strikes Kiriath-sepher and captures it, to him will I give Achsah my daughter as wife.” And Othniel the son of Kenaz, the brother of Caleb, captured it. And he gave him Achsah his daughter as wife.
