He that is born in thy house, and he that is bought with thy money, must needs be circumcised: and my covenant shall be in your flesh for an everlasting covenant.

And God said unto Abraham, As for Sarai thy wife, thou shalt not call her name Sarai, but Sarah shall her name be.
And I will bless her, and give thee a son also of her: yea, I will bless her, and she shall be a mother of nations; kings of people shall be of her.
Then Abraham fell upon his face, and laughed, and said in his heart, Shall a child be born unto him that is an hundred years old? and shall Sarah, that is ninety years old, bear?
And Abraham said unto God, O that Ishmael might live before thee!
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.
And as for Ishmael, I have heard thee: Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly; twelve princes shall he beget, and I will make him a great nation.
But my covenant will I establish with Isaac, which Sarah shall bear unto thee at this set time in the next year.

And Abraham took Ishmael his son, and all that were born in his house, and all that were bought with his money, every male among the men of Abraham's house; and circumcised the flesh of their foreskin in the selfsame day, as God had said unto him.
And Abraham was ninety years old and nine, when he was circumcised in the flesh of his foreskin.
And Ishmael his son was thirteen years old, when he was circumcised in the flesh of his foreskin.
In the selfsame day was Abraham circumcised, and Ishmael his son.
And all the men of his house, born in the house, and bought with money of the stranger, were circumcised with him.
And the LORD appeared unto him in the plains of Mamre: and he sat in the tent door in the heat of the day;
And he lift up his eyes and looked, and, lo, three men stood by him: and when he saw them, he ran to meet them from the tent door, and bowed himself toward the ground,
And said, My Lord, if now I have found favour in thy sight, pass not away, I pray thee, from thy servant:
Let a little water, I pray you, be fetched, and wash your feet, and rest yourselves under the tree:
And I will fetch a morsel of bread, and comfort ye your hearts; after that ye shall pass on: for therefore are ye come to your servant. And they said, So do, as thou hast said.
