What does Genesis 24:40 mean?
Abraham's servant is describing in great detail to Rebekah and her family the reason for his journey to their home. Abraham has sent the servant back to his people to find a wife for his son Isaac (Genesis 24:3–4).The servant recalled, in the previous verse, challenging Abraham with the possibility that an eligible bride, once located, might not be willing to move away from her family to live in the land of Canaan with an unknown husband (Genesis 24:5–8).
Now he shares Abraham's response: The Lord will intervene. More specifically, the Lord will send an angel to give the mission success. Abraham knows this because he himself has walked with the Lord. Abraham insists that the servant will succeed: He will take a wife for Isaac from among Abraham's people. As the servant will explain, he has also seen evidence that God is working to bring Rebekah back to Canaan.
