Genesis 24:37-41

37My master made me swear an oath. He said, ‘You must not acquire a wife for my son from the daughters of the Canaanites, among whom I am living,

38but you must go to the family of my father and to my relatives to find a wife for my son.’

39But I said to my master, ‘What if the woman does not want to go with me?’

40He answered, ‘The Lord, before whom I have walked, will send his angel with you. He will make your journey a success and you will find a wife for my son from among my relatives, from my father’s family.

41You will be free from your oath if you go to my relatives and they will not give her to you. Then you will be free from your oath.’
