Judges 1:11-13

From there [the tribe of] Judah went against the inhabitants of Debir (the name of Debir formerly was Kiriath-sepher [city of books and scribes]). And Caleb said, “Whoever attacks Kiriath-sepher and captures it, I will even give him my daughter Achsah as a wife.” Othniel the son of Kenaz, Caleb’s younger brother, captured it; so he gave him his daughter Achsah as a wife.
