Darby(i)
11 And he received [the] sign of circumcision [as] seal of the righteousness of faith which [he had] being in uncircumcision, that he might be [the] father of all them that believe being in uncircumcision, that righteousness might be reckoned to them also;
12 and father of circumcision, not only to those who are of [the] circumcision, but to those also who walk in the steps of the faith, during uncircumcision, of our father Abraham.
13 For [it was] not by law that the promise was to Abraham, or to his seed, that he should be heir of [the] world, but by righteousness of faith.
