Genesis 24:17-21

Then the servant ran to meet her, and said, “Please let me drink a little water from your jar.”

And she said, “Drink, my lord”; then she quickly lowered her jar to her hand, and gave him a drink.

Now when she had finished giving him a drink, she said, “I will also draw water for your camels until they have finished drinking.”

So she quickly emptied her jar into the trough, and ran back to the well to draw, and she drew for all his camels.

Meanwhile, the man was taking a close look at her in silence, to find out whether the Lord had made his journey successful or not.
