Genesis 24:14-15

14And let it come to pass, [that] the maiden to whom I shall say, Let down thy pitcher, I pray thee, that I may drink, and who will say, Drink, and I will give thy camels drink also, be she whom thou hast appointed for thy servant Isaac; and hereby I shall know that thou hast dealt kindly with my master.

15And it came to pass before he had ended speaking, that behold, Rebecca came out, who was born to Bethuel, son of Milcah the wife of Nahor, Abraham's brother; and [she had] her pitcher upon her shoulder.
