What does Genesis 24:27 mean?
When Rebekah reveals that her grandfather is Abraham's brother Nahor, the servant recognizes that God has indeed answered his prayers and brought him right to the doorstep of Isaac's future wife. He stops in the middle of his conversation with Rebekah and worships the Lord.His prayer reveals his heart. First, the servant blesses the Lord, addressing him once more as the God of his master. Next, he expresses his gratitude and relief that God still has steadfast love and faithfulness for his master. The servant was clearly concerned that if this mission failed, it would suggest that God was no longer concerned with Abraham.
Finally, the servant includes himself in the prayer, giving God the credit for leading him not only to some distant relation of Abraham's, but to Abraham's own immediate family relations.
One note: It was apparently common in this era and in Abraham's family for close relatives to marry each other. This early in human history, there was apparently little risk of genetic issues resulting from the offspring of family members, and God had not yet forbid Israel from marriages between close relatives. In fact, it will become clear that God very much intended for Isaac to marry his cousin Rebekah for the purpose of creating a people that were uniquely His own.
Genesis 24:10–27 follows Abraham's servant from Canaan to Mesopotamia on his mission to find a wife for Isaac from among Abraham's people. Arriving at the town of Nahor, the servant prays that God will reveal the right woman by allowing her to be the one to offer to water his ten camels without being asked. A young woman named Rebekah immediate does exactly that. When the servant learns this young woman is also the granddaughter of Abraham's brother Nahor, he quickly worships God for bringing him to the right woman in so little time.
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.
