Romans 4:10-12

Young's Literal Translation

¹⁰ how then was it reckoned? he being in circumcision, or in uncircumcision? not in circumcision, but in uncircumcision;

¹¹ and a sign he did receive of circumcision, a seal of the righteousness of the faith in the uncircumcision, for his being father of all those believing through uncircumcision, for the righteousness also being reckoned to them,

¹² and father of circumcision to those not of circumcision only, but who also walk in the steps of the faith, that [is] in the uncircumcision of our father Abraham.
