Genesis 24:12-14

He prayed: “YAHWEH, God of my master Abraham, let my journey here be a success and show your gracious love to my master Abraham. I am standing here by this well, and the young women of the village are coming out to draw water. Give me a sign. I will say to one of the girls, ‘Please, lower your jar and give me a drink.’ And if she is the right one, the girl whom you have chosen to be a wife for your servant Isaac, then let her say to me, ‘Drink, and I will also draw water for your camels.’ By this sign I will know that you have shown your gracious love to my master.”
