Genesis 24:42 (KJV)

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.
