'Uncircumcision' in the Bible

But contrariwise, when they saw that the gospel of the uncircumcision was committed unto me, as the gospel of the circumcision was unto Peter;

For in Jesus Christ neither circumcision availeth any thing, nor uncircumcision; but faith which worketh by love.

For in Christ Jesus neither circumcision availeth any thing, nor uncircumcision, but a new creature.
