Genesis 24:18-21

So she said, “Drink, my lord.” Then she quickly let her pitcher down to her hand, and gave him a drink. And when she had finished giving him a drink, she said, “I will draw water for your camels also, until they have finished drinking.” Then she quickly emptied her pitcher into the trough, ran back to the well to draw water, and drew for all his camels. And the man, wondering at her, remained silent so as to know whether the LORD had made his journey prosperous or not.
