Genesis 24:39 (KJV)

And he said, I am Abraham's servant.

And the LORD hath blessed my master greatly; and he is become great: and he hath given him flocks, and herds, and silver, and gold, and menservants, and maidservants, and camels, and asses.

And Sarah my master's wife bare a son to my master when she was old: and unto him hath he given all that he hath.

And my master made me swear, saying, Thou shalt not take a wife to my son of the daughters of the Canaanites, in whose land I dwell:

But thou shalt go unto my father's house, and to my kindred, and take a wife unto my son.

And he said unto me, The LORD, before whom I walk, will send his angel with thee, and prosper thy way; and thou shalt take a wife for my son of my kindred, and of my father's house:

Then shalt thou be clear from this my oath, when thou comest to my kindred; and if they give not thee one, thou shalt be clear from my oath.

And I came this day unto the well, and said, O LORD God of my master Abraham, if now thou do prosper my way which I go:

Behold, I stand by the well of water; and it shall come to pass, that when the virgin cometh forth to draw water, and I say to her, Give me, I pray thee, a little water of thy pitcher to drink;

And she say to me, Both drink thou, and I will also draw for thy camels: let the same be the woman whom the LORD hath appointed out for my master's son.
