Genesis 24:18-21

She said, “Drink, my lord.” And she quickly let down her jar upon her hand and gave him a drink. When she had finished giving him a drink, she said, “I will draw water for your camels also, until they have finished drinking.” So she quickly emptied her jar into the trough and ran again to the well to draw water, and she drew for all his camels. The man gazed at her in silence to learn whether the LORD had prospered his journey or not.
