What does Genesis 24:15 mean?
Abraham's unnamed servant is on a mission to find a wife for Abraham's son, Isaac. He has been sent specifically to Abraham's extended family in Mesopotamia. His first stop is at a town named for one of Abraham's relatives. There, he prays for God to give him a sign about which woman he should bring home for Isaac. Specifically, he is seeking a woman with a generous spirit. His prayer involves asking for water, and seeing if a woman volunteers to also bring water for his camels—not a small task.Even before Abraham's servant has concluded the prayer described in the previous verses (Genesis 24:12–14), Rebekah walks into view carrying a water jar on her shoulder. God immediately responded to the servant's sincere prayer to show love to Abraham by showing the servant the appointed girl.
Rebekah is the granddaughter of Nahor, Abraham's brother (Genesis 11:27). Her father Bethuel was born to Nahor's wife Milcah (Genesis 22:20–23). The servant did not yet know all of that, but this means that not only will Isaac's wife be from among Abraham's clan, she will be of his more immediate family.
