What did Caleb say he'd give to whoever could smite Kirjathsepher?


His daughter Achsah for a wife

And Caleb said, He that smiteth Kirjathsepher, and taketh it, to him will I give Achsah my daughter to wife. Joshua 15:16

(Caleb's nephew, Othniel, smote Kirjathsepher and got Caleb's daughter for a wife.)
And Othniel the son of Kenaz, the brother of Caleb, took it: and he gave him Achsah his daughter to wife. Joshua 15:17
The same story is told in the book of Judges.

And Caleb said, He that smiteth Kirjathsepher, 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. Judges 1:12-13
