Besides this wonderful agreement between the types and the things typified, the adversary may be convinced by plain prophetic intimations, such as this: "In thy seed shall all nations be blessed." This was said to Abraham, ¹ and again to Isaac, ² and again to Jacob. ³ Hence the significance of the words "I am the God of Abraham, and Isaac, and Jacob." ⁴ God fulfills His promise to their seed in blessing all nations. With a like significance, Abraham himself, when he made his servant swear, told him to put his hand under his thigh; ⁵ for he knew that thence would come the flesh of Christ, in whom we have now, not the promise of blessing to all nations, but the promise fulfilled.
