Joshua 15:15-17

And he went up thence to the inhabitants of Debir: and the name of Debir before was Kirjath-sepher. And Caleb said, He that smiteth Kirjath-sepher, and taketh it, to him will I give Achsah my daughter to wife. And Othniel the son of Kenaz, the brother of Caleb, took it: and he gave him Achsah his daughter to wife.
