Genesis 24:2-4

New Revised Standard Version, Anglicised Catholic Edition

² Abraham said to his servant, the oldest of his house, who had charge of all that he had, ‘Put your hand under my thigh ³ and I will make you swear by the Lord, the God of heaven and earth, that you will not get a wife for my son from the daughters of the Canaanites, among whom I live, ⁴ but will go to my country and to my kindred and get a wife for my son Isaac.’
