Genesis 17:9-14

17:9 Then God said to Abraham, “As for you, you must keep the covenantal requirement I am imposing on you and your descendants after you throughout their generations. 17:10 This is my requirement that you and your descendants after you must keep: Every male among you must be circumcised. 17:11 You must circumcise the flesh of your foreskins. This will be a reminder of the covenant between me and you. 17:12 Throughout your generations every male among you who is eight days old must be circumcised, whether born in your house or bought with money from any foreigner who is not one of your descendants. 17:13 They must indeed be circumcised, whether born in your house or bought with money. The sign of my covenant will be visible in your flesh as a permanent reminder. 17:14 Any uncircumcised male who has not been circumcised in the flesh of his foreskin will be cut off from his people – he has failed to carry out my requirement.”

John 7:22

7:22 However, because Moses gave you the practice of circumcision (not that it came from Moses, but from the forefathers), you circumcise a male child on the Sabbath.

Romans 4:10

4:10 How then was it credited to him? Was he circumcised at the time, or not? No, he was not circumcised but uncircumcised!

Galatians 3:15

Inheritance Comes from Promises and not Law

3:15 Brothers and sisters, I offer an example from everyday life: When a covenant has been ratified, even though it is only a human contract, no one can set it aside or add anything to it.

Galatians 3:17

3:17 What I am saying is this: The law that came four hundred thirty years later does not cancel a covenant previously ratified by God, so as to invalidate the promise.
