'Person' in the Bible

Therefore, if the uncircumcised person follows the requirements of the law, will not his uncircumcision be credited for circumcision?

And the uncircumcised person by nature who carries out the law will judge you who, [though provided] with {the precise written code} and circumcision [are] a transgressor of the law.

For by the works of the law {no person will be declared righteous} before him, for through the law [comes] knowledge of sin.

in the forbearance of God, for the demonstration of his righteousness in the present time, so that he should be just and the one who justifies the [person] by faith in Jesus.

For we consider a person to be justified by faith apart from the works of the law.

just as David also speaks about the blessing of the person to whom God credits righteousness apart from works:

Blessed [is] the person against whom the Lord will never count sin."

For only rarely will someone die on behalf of a righteous person (for on behalf of a good person possibly someone might even dare to die),

Or do you not know, brothers (for I am speaking to those who know the law), that the law is master of a person for as long a time [as] he lives?

For I joyfully agree with the law of God in my inner person,

But you are not in the flesh but in the Spirit, if indeed the Spirit of God lives in you. But if anyone does not have the Spirit of Christ, this person {does not belong to him}.

For Moses writes about the righteousness [that is] from the law: "The person who does [this] will live by it."

Let every person be subject to the governing authorities, for [there] is no authority except by God, and those that exist are put in place by God.

One person prefers [one] day over [another] day, and another person regards every day [alike]. Each one must be fully convinced in his own mind.

I know and am convinced in the Lord Jesus that nothing [is] unclean of itself, except to the one who considers something to be unclean; to that person [it is] unclean.

For if because of food, your brother is grieved, you are no longer living according to love. Do not destroy by your food that person for whom Christ died.

Do not destroy the work of God on account of food. All [things] [are] clean, but [it is] wrong for the person {who eats and stumbles in the process}.
