Judges 1:11-15

11From there they marched against the inhabitants of Debir (formerly known as Kiriath-sepher). 12And Caleb said, “To the man who strikes down Kiriath-sepher and captures it, I will give my daughter Acsah in marriage.” 13So Othniel son of Caleb’s younger brother Kenaz captured the city, and Caleb gave his daughter Acsah to him in marriage.

14One day Acsah came to Othniel and urged him1 to ask her father for a field. When she got off her donkey, Caleb asked her, “What do you desire?”

15“Give me a blessing,” she answered. “Since you have given me land in the Negev, give me springs of water as well.”

So Caleb gave her both the upper and lower springs.
