Genesis 24:12-15

And he said, “O LORD, God of my master Abraham, please grant me success today, and show lovingkindness (faithfulness) to my master Abraham. Behold, I stand here at the spring of water, and the daughters of the men of the city are coming out to draw water; now let it be that the girl to whom I say, ‘Please, let down your jar so that I may [have a] drink,’ and she replies, ‘Drink, and I will also give your camels water to drink’—may she be the one whom You have selected [as a wife] for Your servant Isaac; and by this I will know that You have shown lovingkindness (faithfulness) to my master.” Before Eliezer had finished speaking (praying), Rebekah came out with her [water] jar on her shoulder. Rebekah was the daughter of Bethuel the son of Milcah, who was the wife of Abraham’s brother Nahor.
