'Person' in the Bible

but I was unknown {in person} to the churches of Judea [that are] in Christ,

but knowing that a person is not justified by the works of the law, if not by faith in Jesus Christ, and we have believed in Christ Jesus so that we may be justified by faith in Christ and not by the works of the law, because by the works of the law {no human being will be justified}.

Brothers, even if a person is caught in some trespass, you [who are] spiritual restore such a person in a spirit of humility, looking out for yourself, lest you also be tempted.

Do not be deceived: God is not to be mocked, for whatever a person sows, this he will also reap,
