Genesis 24:1-6 KJV

1 And Abraham was old , and well stricken in age: and the LORD had blessed Abraham in all things.
2 And Abraham said unto his eldest servant 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 the LORD, the God of heaven, and the God of the earth, that thou shalt not take a wife unto 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 unto 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 .
