Genesis 24:12-14

Then he prayed, ‘LORD, God of my master Abraham, make me successful today, and show kindness to my master Abraham. See, I am standing beside this spring, and the daughters of the townspeople are coming out to draw water. May it be that when I say to a young woman, “Please let down your jar that I may have a drink,” and she says, “Drink, and I’ll water your camels too” – let her be the one you have chosen for your servant Isaac. By this I will know that you have shown kindness to my master.’
