Genesis 24:42 (KJV)

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 I said unto my master, Peradventure the woman will not follow me.

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.

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.

And before I had done speaking in mine heart, behold, Rebekah came forth with her pitcher on her shoulder; and she went down unto the well, and drew water: and I said unto her, Let me drink, I pray thee.

And she made haste, and let down her pitcher from her shoulder, and said, Drink, and I will give thy camels drink also: so I drank, and she made the camels drink also.

And I asked her, and said, Whose daughter art thou? And she said, the daughter of Bethuel, Nahor's son, whom Milcah bare unto him: and I put the earring upon her face, and the bracelets upon her hands.
