GEN 24:14

14 I am asking you this: ‘I will say to some girl, “Please lower your jar so that I may drink some water.” If she says, “Drink some, and I will draw some water [from the well] for your camels, too,” I will know that she is the woman whom you chose to be a wife for your servant, Isaac, and I will know that you have been kind to my master.’”
