And Abram and Nahor took wives: the name of Abram's wife was Sarai, and the name of Nahor's wife, Milcah, the daughter of Haran the father of Milcah and the father of Iscah.

But Sarai was barren; she had no child.

Then God said to Abraham, As for Sarai your wife, you shall not call her name Sarai, but Sarah shall be her name.

Then Abraham fell on his face and laughed, and said in his heart, Shall one be born to a man who is one hundred years old? And shall Sarah, who is ninety years old, give birth?

And God said: Truly, Sarah your wife shall bear you a son, and you shall call his name Isaac; I have established My covenant with him for a perpetual covenant, with his seed after him.

And He said, I will come back to return to you according to the time of life, and behold, Sarah your wife shall have a son. And Sarah was listening from the tent opening which was behind him.

Therefore Sarah laughed within herself, saying, Being worn out, shall I be delighted, my lord, having also become old?

Is anything beyond the power of Jehovah? At the appointed time I will return to you, according to the time of life, and Sarah shall have a son.

And Jehovah visited Sarah as He had said, and Jehovah did for Sarah as He had spoken.

And Abraham called the name of his son who was born to him, whom Sarah had borne to him, Isaac.

And Abraham was one hundred years old when his son Isaac was born to him.

She also said, Who would have said to Abraham that Sarah would suckle a son? For I have borne him a son in his old age.

And not being weak in faith, he did not consider his own body, already dead (since he was about a hundred years old), and the deadness of Sarah's womb;

Therefore she said to Abraham, Drive away this maidservant and her son; for the son of this maidservant shall not inherit with my son, with Isaac.

And Abraham gave all that he had to Isaac.
