And the LORD said to Abraham, "Why did Sarah laugh, saying, 'Shall I surely bear [a child,] since I am old?'

"Is anything too hard for the LORD? At the appointed time I will return to you, according to the time of life, and Sarah shall have a son."

Then the Angel of the LORD said to her, "I will multiply your descendants exceedingly, so that they shall not be counted for multitude."

Then the Angel of the LORD called to Abraham a second time out of heaven,

and said: "By Myself I have sworn, says the LORD, because you have done this thing, and have not withheld your son, your only [son -- ]

"But My covenant I will establish with Isaac, whom Sarah shall bear to you at this set time next year."

For Sarah conceived and bore Abraham a son in his old age, at the set time of which God had spoken to him.

Then he said, "About this time next year you shall embrace a son." And she said, "No, my lord. Man of God, do not lie to your maidservant!"

But the woman conceived, and bore a son when the appointed time had come, of which Elisha had told her.

"And I will bless her and also give you a son by her; then I will bless her, and she shall be [a mother of] nations; kings of peoples shall be from her."

Then God said: "No, Sarah your wife shall bear you a son, and you shall call his name Isaac; I will establish My covenant with him for an everlasting covenant, [and] with his descendants after him.

"But My covenant I will establish with Isaac, whom Sarah shall bear to you at this set time next year."

For Sarah conceived and bore Abraham a son in his old age, at the set time of which God had spoken to him.

And the Angel of the LORD appeared to the woman and said to her, "Indeed now, you are barren and have borne no children, but you shall conceive and bear a son.

"For behold, you shall conceive and bear a son. And no razor shall come upon his head, for the child shall be a Nazirite to God from the womb; and he shall begin to deliver Israel out of the hand of the Philistines."

But the angel said to him, "Do not be afraid, Zacharias, for your prayer is heard; and your wife Elizabeth will bear you a son, and you shall call his name John.

That is, those who [are] the children of the flesh, these [are] not the children of God; but the children of the promise are counted as the seed.

For this [is] the word of promise: "At this time I will come and Sarah shall have a son."

But he [who was] of the bondwoman was born according to the flesh, and he of the freewoman through promise,

Now we, brethren, as Isaac [was,] are children of promise.
