Genesis 24:2 YLT

¹  And Abraham 'is' old, he hath entered into days, and Jehovah hath blessed Abraham in all 'things';

²  and Abraham saith unto his servant, the eldest of his house, who is ruling over all that he hath, 'Put, I pray thee, thy hand under my thigh,

³  and I cause thee to swear by Jehovah, God of the heavens, and God of the earth, that thou dost not take a wife for my son from the daughters of the Canaanite, in the midst of whom I am dwelling;

⁴  but unto my land and unto my kindred dost thou go, and hast taken a wife for my son, for Isaac.'
