Judges 1:11-13
11 From there they advanced against the people living in Debir (formerly called Kiriath Sepher).
12 And Caleb said, “I will give my daughter Acsah in marriage to the man who attacks and captures Kiriath Sepher.”
13 Othniel son of Kenaz, Caleb’s younger brother, took it; so Caleb gave his daughter Acsah to him in marriage.
