Genesis 24:37-41

37And my master made me swear, saying, Thou shalt not take a wife for my son of the daughters of the Canaanite, in whose land I am dwelling;

38but thou shalt by all means go to my father's house and to my family, and take a wife for my son.

39And I said to my master, Perhaps the woman will not follow me?

40And he said to me, Jehovah, before whom I have walked, will send his angel with thee, and prosper thy way, that thou mayest take a wife for my son of my family, and out of my father's house.

41Then shalt thou be quit of my oath, when thou shalt have come to my family. And if they give thee not [one], thou shalt be quit of my oath.
