Genesis 24:10-14

10Then the servant took ten of his master's camels and departed, taking all sorts of choice gifts from his master; and he arose and went to Mesopotamia to the city of Nahor.

11And he made the camels kneel down outside the city by the well of water at the time of evening, the time when women go out to draw water.

12And he said, "O Lord, God of my master Abraham, please grant me success today and show steadfast love to my master Abraham.

13Behold, I am standing by the spring of water, and the daughters of the men of the city are coming out to draw water.

14Let the young woman to whom I shall say, 'Please let down your jar that I may drink,' and who shall say, 'Drink, and I will water your camels'—let her be the one whom you have appointed for your servant Isaac. By this I shall know that you have shown steadfast love to my master."
