Genesis 24:13-14

13See, I am standing here beside this spring, and the young women of the town are coming out to draw water.

14This is my request. I will ask one of them, ‘Please give me a drink from your jug.’ If she says, ‘Yes, have a drink, and I will water your camels, too!’—let her be the one you have selected as Isaac’s wife. This is how I will know that you have shown unfailing love to my master.”
