Genesis 24:3-5

American Standard Version

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?
