'Circumcision' in the Bible

And this is the agreement which you are to keep with me, you and your seed after you: every male among you is to undergo circumcision.

Every male among you, from one generation to another, is to undergo circumcision when he is eight days old, with every servant whose birth takes place in your house, or for whom you gave money to someone of another country, and not of your seed.

He who comes to birth in your house and he who is made yours for a price, all are to undergo circumcision; so that my agreement may be marked in your flesh, an agreement for all time.

And any male who does not undergo circumcision will be cut off from his people: my agreement has been broken by him.

And Abraham took Ishmael, his son, and all whose birth had taken place in his house, and all his servants whom he had made his for a price, every male of his house, and on that very day he gave them circumcision in the flesh of their private parts as God had said to him.

Abraham was ninety-nine years old when he underwent circumcision.

And Ishmael, his son, was thirteen years old when he underwent circumcision.

Abraham and Ishmael, his son, underwent circumcision on that very day.

And all the men of his house, those whose birth had taken place in the house and those whom he had got for money from men of other lands, underwent circumcision with him.

And when his son Isaac was eight days old, Abraham made him undergo circumcision, as God had said to him.

And they said, It is not possible for us to give our sister to one who is without circumcision, for that would be a cause of shame to us:

But on this condition only will we come to an agreement with you: if every male among you becomes like us and undergoes circumcision;

But if you will not undergo circumcision as we say, then we will take our daughter and go.

But these men will make an agreement with us to go on living with us and to become one people, only on the condition that every male among us undergoes circumcision as they have done.

Then all the men of the town gave ear to the words of Hamor and Shechem his son; and every male in the town underwent circumcision.

Now on the third day [after the circumcision], when all the men were [terribly] sore and in pain, two of Jacob’s sons, Simeon and Levi, Dinah’s [full] brothers, took their swords, boldly entered the city [without anyone suspecting them of evil intent], and they killed every male.
