The Son Of Promise - God Will Do, What He Says He Will Do, Genesis 20-23.

And the Lord  visited Sarah as He had said, and the Lord did for Sarah as He had spoken. For Sarah conceived and bore Abraham a son in his old age, at the set time of which God had spoken to him. And Abraham called the name of his son who was born to him—whom Sarah bore to him— Isaac. And Sarah said, “God has made me laugh, and all who hear will laugh with me.” So the child grew and was weaned. And Abraham made a great feast on the same day that Isaac was weaned. And Sarah saw the son of Hagar the Egyptian, whom she had borne to Abraham, scoffing. And God heard the voice of the lad. Then the angel of God called to Hagar out of heaven, and said to her, “What ails you, Hagar? Fear not, for God has heard the voice of the lad where he is. Arise, lift up the lad and hold him with your hand, for I will make him a great nation.” Now it came to pass after these things that God tested Abraham, and said to him, “Abraham!” And he said, “Here I am.” Then He said, “Take now your son, your only son Isaac, whom you love, and go to the land of Moriah, and offer him there as a burnt offering on one of the mountains of which I shall tell you.” But Isaac spoke to Abraham his father and said, “My father!” And he said, “Here I am, my son.” Then he said, “Look, the fire and the wood, but where is the lamb for a burnt offering?” Sarah lived one hundred and twenty-seven years; these were the years of the life of Sarah. So Sarah died in Kirjath Arba (that is,  Hebron) in the land of Canaan, and Abraham came to mourn for Sarah and to weep for her.
