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 Canaanites, in whose land I dwell: 38But thou shalt go to my father’s house, and to my kindred, and take a wife for my son. 39And I said to my master, It may be the woman will not follow me. 40And he said to 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: 41Then 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.
