Abraham now old, Isaac to take a wife

1 Now Abraham was old, and advanced in age; and the Lord had blessed him in all things. 2 And he said to the elder servant of his house [Eliezer], who was ruler over all he had: Put thy hand under my thigh, 3 That I may make thee swear by the Lord, the God of heaven and earth, that thou take not a wife for my son, of the daughters of the Chanaanites, among whom I dwell: 4 But that thou go to my own country and kindred, and take a wife from thence for my son Isaac.

9 The servant, therefore, put his hand under the thigh of Abraham, his lord, and swore to him upon his word.
