¹⁹ And God said, Sarah thy wife shall bear thee a son indeed; and thou shalt call his name Isaac: and I will establish my covenant with him for an everlasting covenant, and with his seed after him.

¹¹ The Lord hath sworn in truth unto David; he will not turn from it; Of the fruit of thy body will I set upon thy throne.

²⁰ Thou wilt perform the truth to Jacob, and the mercy to Abraham, which thou hast sworn unto our fathers from the days of old.

⁵⁵ As he spake to our fathers, to Abraham, and to his seed for ever.

¹³ For the promise, that he should be the heir of the world, was not to Abraham, or to his seed, through the law, but through the righteousness of faith.

¹⁶ Therefore it is of faith, that it might be by grace; to the end the promise might be sure to all the seed; not to that only which is of the law, but to that also which is of the faith of Abraham; who is the father of us all,

⁴ Who are Israelites; to whom pertaineth the adoption, and the glory, and the covenants, and the giving of the law, and the service of God, and the promises;

⁸ That is, They which are the children of the flesh, these are not the children of God: but the children of the promise are counted for the seed.

²⁹ And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise.

²⁸ Now we, brethren, as Isaac was, are the children of promise.
