Genesis 24:2-4

Darby Translation

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

³ and I will make thee swear by Jehovah, the God of the heavens and the God of the earth, that thou take not a wife for my son of the daughters of the Canaanites, among whom I am dwelling;

⁴ but thou shalt go to my land and to my kindred, and take a wife for my son Isaac.
