Judges 1:11-13

And from thence he went against 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, Caleb's younger brother, took it: and he gave him Achsah his daughter to wife.
