Genesis 24:39

36 Sarah, my master`s wife, bore a son to my master when she was old. He has given all that he has to him.

37 My master made me swear, saying, `You shall not take a wife for my son of the daughters of the Canaanites, in whose land I live,

38 but you shall go to my father`s house, and to my relatives, and take a wife for my son.`

39 I said to my master, `What if the woman will not follow me?`

40 He said to me, `Yahweh, before whom I walk, will send his angel with you, and prosper your way. You shall take a wife for my son of my relatives, and of my father`s house.

41 Then will you be clear from my oath, when you come to my relatives. If they don`t give her to you, you shall be clear from my oath.`

42 I came this day to the spring, and said, `Yahweh, the God of my master Abraham, if now you do prosper my way which I go.
