12He who is aeight days old among you shall be circumcised. Every male throughout your generations, whether born in your house or bbought with your money from any foreigner who is not of your offspring,

Romans 4:11-13

11 cHe received the sign of circumcision as a seal of the righteousness that he had by faith while he was still uncircumcised. The purpose was dto 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.

The Promise Realized Through Faith

13For ethe promise to Abraham and his offspring fthat he would be heir of the world did not come through the law but through the righteousness of faith.
