Genesis 24:11-14 King James Version (KJV)
11 And 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.
12 And 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.
13 Behold, I stand here by the well of water; and the daughters of the men of the city come out to draw water:
14 And 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.
