Achsah (Hebrew: עַכְסָה) was the wife of the Israelite judge Othniel and the daughter of Caleb. Caleb sought the conquest of Debir (Kiriath-sepher) for his tribe and promised his daughter Achsah to the person who captures the city.
I will give Achsah my daughter as wife to the man who attacks Kiriath-sepher and captures it.— Joshua 15:16 (AMP)
Whoever attacks Kiriath-sepher and captures it, I will even give him my daughter Achsah as a wife.— Judges 1:12 (AMP)
Othniel took up the challenge and conquered the city. Thus, Othniel won Achsah's hand in marriage. Achsah then persuaded Caleb to grant her and her husband a field and then some springs to water it with.
Give me a blessing; since you have given me the [dry] land of the Negev (South country), give me springs of water, too.— Joshua 15:19 (AMP)
