Genesis 17:5-11

5No longer shall your name be called Abram,
 Abram means exalted father
but byour name shall be Abraham,
 Abraham means father of a multitude
dfor I have made you the father of a multitude of nations.
6I will make you exceedingly fruitful, and I will make eyou into nations, and fkings shall come from you. 7And I will gestablish my covenant between me and you and your offspring after you throughout their generations for an everlasting covenant, hto be God to you and to your offspring after you. 8And iI will give to you and to your offspring after you the land of your sojournings, all the land of Canaan, for an everlasting possession, and jI will be their God.”

9And God said to Abraham, “As for you, you shall keep my covenant, you and your offspring after you throughout their generations. 10This is my covenant, which you shall keep, between me and you and your offspring after you: Every male among you shall be circumcised. 11You shall be circumcised in the flesh of your foreskins, and it shall be a ksign of the covenant between me and you.

Deuteronomy 30:6

Jeremiah 4:4

4 pCircumcise yourselves to the Lord;
remove the foreskin of your hearts,
O men of Judah and inhabitants of Jerusalem;
qlest my wrath go forth like fire,
and burn with none to quench it,
rbecause of the evil of your deeds.”

Jeremiah 9:26

26 sEgypt, Judah, Edom, the sons of Ammon, Moab, and tall who dwell in the desert who cut the corners of their hair, for all these nations are uncircumcised, and all the house of Israel are uuncircumcised in heart.”

Romans 2:25-29

25For circumcision indeed is of value vif you obey the law, but if you break the law, your circumcision becomes uncircumcision. 26So, if wa man who is uncircumcised keeps xthe precepts of the law, will not his uncircumcision be regarded
Or counted
as circumcision?
27Then he who is physically
Or  is by nature
uncircumcised but keeps the law aawill condemn you who have abthe written code
Or  the letter
and circumcision but break the law.
28For adno one is a Jew aewho is merely one outwardly, nor is circumcision outward and physical. 29But a Jew is one afinwardly, and agcircumcision is a matter of the heart, by the Spirit, not by the letter. ahHis praise is not from man but from God.

Romans 4:11-12

11 aiHe received the sign of circumcision as a seal of the righteousness that he had by faith while he was still uncircumcised. The purpose was ajto make him the father of all who believe without being circumcised, so that righteousness would be counted to them as well, 12and to make him the father of the circumcised who are not merely circumcised but who also walk in the footsteps of the faith that our father Abraham had before he was circumcised.
