God's Gifts Are Irrevocable - Joshua 15-16

And Caleb said, “He who attacks Kirjath Sepher and takes it, to him I will give Achsah my daughter as wife.” So Othniel the son of Kenaz, the brother of Caleb, took it; and he gave him Achsah his daughter as wife. Now it was so, when she came to him, that she persuaded him to ask her father for a field. So she dismounted from her donkey, and Caleb said to her, “What do you wish?” She answered, “Give me a blessing; since you have given me land in the South, give me also springs of water.” So he gave her the upper springs and the lower springs.
