Achsah bat Caleb, also Acsah, was Caleb ben Yefune's only daughter. She was offered in marriage to the man who would lead an attack on the city of Debir, also called Kirjath-sepher/Kirjath-sannah. This was done by Othniel, Caleb's nephew or younger brother, who accordingly was permitted to marry her (Joshua 15:16-19; Judges 1:9-15).
