Genesis 24:3

1 And Abraham was old, [and] well stricken in age. And Jehovah had blessed Abraham in all things.

2 And Abraham said unto his servant, the elder of his house, that ruled over all that he had, Put, I pray thee, thy hand under my thigh.

3 And I will make thee swear by Jehovah, the God of heaven and the God of the earth, that thou wilt not take a wife for my son of the daughters of the Canaanites, among whom I dwell.

4 But thou shalt go unto my country, and to my kindred, and take a wife for my son Isaac.

5 And the servant said unto him, Peradventure the woman will not be willing to follow me unto this land. Must I needs bring thy son again unto the land from whence thou camest?

6 And Abraham said unto him, Beware thou that thou bring not my son thither again.

7 Jehovah, the God of heaven, who took me from my father`s house, and from the land of my nativity, and who spake unto me, and who sware unto me, saying, Unto thy seed will I give this land. He will send his angel before thee, and thou shalt take a wife for my son from thence.
