Genesis 24:18-20

18“Drink, my lord,” she said, and quickly lowered the jar to her hands and gave him a drink. 19After she had given him a drink, she said, “I’ll draw water for your camels too, until they have had enough to drink.” 20So she quickly emptied her jar into the trough, ran back to the well to draw more water, and drew enough for all his camels.
