Genesis 24:13

11And he made his camels to kneel down without the city by a well of water at the time of the evening, even the time that women go out to draw water.

12And he said O LORD God of my master Abraham, I pray thee, send me good speed this day, and shew kindness unto my master Abraham.

13Behold, I stand here by the well of water; and the daughters of the men of the city come out to draw water:

14And let it come to pass, that the damsel to whom I shall say, Let down thy pitcher, I pray thee, that I may drink; and she shall say, Drink, and I will give thy camels drink also: let the same be she that thou hast appointed for thy servant Isaac; and thereby shall I know that thou hast shewed kindness unto my master.

15And it came to pass, before he had done speaking, that, behold, Rebekah came out, who was born to Bethuel, son of Milcah, the wife of Nahor, Abraham’s brother, with her pitcher upon her shoulder.
