Genesis 24:37-41

³⁷And 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: ³⁸But thou shalt go unto my father's house, and to my kindred, and take a wife unto my son. ³⁹And I said unto my master, Peradventure the woman will not follow me. ⁴⁰And 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: 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.
