What does Genesis 24:5 mean?
Abraham has asked his most trusted servant to swear to find a wife for his son Isaac. This man is explicitly charged with finding a woman of Abraham's extended family, in his old homeland outside of Canaan. Before swearing to do so, however, the servant responds with a reasonable objection: What if I find a girl, but she doesn't want to travel away from her family to a strange land to marry a man she's never seen? Should I then take Isaac back to your people to live among them?The servant's question is very reasonable. He needs to know if marrying a girl from Abraham's people is so critical that Isaac should be taken to live in Abraham's former old homeland, if no woman will agree to come to Canaan. Abraham's response will fully resolve that question—his absolutely forbids the servant to allow Isaac to return to Mesopotamia. Abraham does not want to jeopardize, in any way, his descendants' possession of the Promised Land.
Genesis 24:1–9 describes an urgent conversation between Abraham and his most trusted servant. Abraham is asking the servant to swear an oath to find a wife for Isaac from among his own people in Mesopotamia. The servant must not allow Isaac either to marry into a Canaanite family or to leave the promised land of Canaan. With the understanding that he will be released from the oath if no young woman will agree to return with him, the servant swears to find Isaac a wife.
Abraham asks his most trusted servant to travel to his former homeland to find a wife for his son Isaac. Swearing to do so, the servant arrives at the city of Nahor and asks the Lord to show him which young women is appointed for Isaac. Finding Rebekah, the very granddaughter of Abraham's brother Nahor, the servant reveals the reason for his journey to her family. Her father Bethuel and brother Laban agree to allow Rebekah to travel to Canaan and marry Isaac, which she does.
