Hebrews 11:13-22 NKJV

Genesis 21:12 But God said to Abraham, "Do not let it be displeasing in your sight because of the lad or because of your bondwoman. Whatever Sarah has said to you, listen to her voice; for in Isaac your seed shall be called.

Romans 4:13-18 For the promise that he would be the heir of the world was not to Abraham or to his seed through the law, but through the righteousness of faith.

For if those who are of the law are heirs, faith is made void and the promise made of no effect,

because the law brings about wrath; for where there is no law there is no transgression.

Therefore it is of faith that it might be according to grace, so that the promise might be sure to all the seed, not only to those who are of the law, but also to those who are of the faith of Abraham, who is the father of us all

(as it is written, "I have made you a father of many nations") in the presence of Him whom he believed--God, who gives life to the dead and calls those things which do not exist as though they did;

who, contrary to hope, in hope believed, so that he became the father of many nations, according to what was spoken, "So shall your descendants be,"

Genesis 27:26-40 Then his father Isaac said to him, "Come near now and kiss me, my son."

And he came near and kissed him; and he smelled the smell of his clothing, and blessed him and said; "Surely, the smell of my son Is like the smell of a field Which the LORD has blessed.

Therefore may God give you Of the dew of heaven, Of the fatness of the earth, And plenty of grain and wine.

Let peoples serve you, And nations bow down to you. Be master over your brethren. And let you mother's sons bow down to you. Cursed be everyone who curses you. and blessed be those who bless you!"

Now it happened, as soon as Isaac had finished blessing Jacob, and Jacob had scarcely gone out from the presence of Isaac his father, that Esau his brother came in from his hunting.

He also had made savory food, and brought it to his father, and said to his father, "Let my father arise and eat of his son's game, that your soul may bless me."

And his father Isaac said to him, "Who are you?" So he said, "I am your son, your firstborn, Esau."

Then Isaac trembled exceedingly, and said, "Who? Where is the one who hunted game and brought it to me? I ate all of it before you came, and I have blessed him--and indeed he shall be blessed."

When Esau heard the words of his father, he cried with an exceedingly great and bitter cry, and said to his father, "Bless me--me also, O my father!"

But he said, "Your brother came with deceit and has taken away your blessing."

And Esau said, "Is he rightly named Jacob? For he has supplanted me these two times. He took away my birthright, and now look, he has taken away my blessing!" And he said, "Have you not reserved a blessing for me?"

Then Isaac answered and said to Esau, "Indeed I have mad him your master, and all his brethren I have given to him as servants; with grain and wine I have sustained him,. What shall I do now for you, my son?"

And Esau said to his father, "Have you only one blessing, my father? Bless me--me also, O my father!" And Esau lifted up his voice and wept.

Then Isaac his father answered and said to him; "Behold, your dwelling shall be of the fatness of the earth, And of the dew of heaven from above.

By your sword you shall live, and you shall serve your brother; And it shall come to pass, when you become restless, That you shall break his yoke from your neck."
