Now Abraham was old and far on in years: and the Lord had given him everything in full measure.
And Abraham said to his chief servant, the manager of all his property, Come now, put your hand under my leg:
And take an oath by the Lord, the God of heaven and the God of the earth, that you will not get a wife for my son Isaac from the daughters of the Canaanites among whom I am living;
But that you will go into my country and to my relations and get a wife there for my son Isaac.
And the servant said, If by chance the woman will not come with me into this land, am I to take your son back again to the land from which you came?
And Abraham said, Take care that you do not let my son go back to that land.
