WNT(i)
10 What then were the circumstances under which this took place? Was it after he had been circumcised, or before?
11 Before, not after. And he received circumcision as a sign, a mark attesting the reality of the faith-righteousness which was his while still uncircumcised, that he might be the forefather of all those who believe even though they are uncircumcised--in order that this righteousness might be placed to their credit;
12 and the forefather of the circumcised, namely of those who not merely are circumcised, but also walk in the steps of the faith which our forefather Abraham had while he was as yet uncircumcised.
