Genesis 24:36

33 And meat was put before him, but he said, I will not take food till I have made my business clear to you. And they said, Do so.

34 And he said, I am Abraham's servant.

35 The Lord has given my master every blessing, and he has become great: he has given him flocks and herds and silver and gold, and men-servants and women-servants and camels and asses.

36 And when Sarah, my master's wife, was old, she gave birth to a son, to whom he has given all he has.

37 And my master made me take an oath, saying, Do not get a wife for my son from the daughters of the Canaanites among whom I am living;

38 But go to my father's house and to my relations for a wife for my son.

39 And I said to my master, What if the woman will not come with me?
