'Man' in the Bible

Therefore if the uncircumcised man obeys the righteous requirements of the law, will not his uncircumcision be regarded as circumcision?

And will not the physically uncircumcised man who keeps the law judge you who, despite the written code and circumcision, transgress the law?

So even David himself speaks regarding the blessedness of the man to whom God credits righteousness apart from works:

So then, just as sin entered the world through one man and death through sin, and so death spread to all people because all sinned --

But the gracious gift is not like the transgression. For if the many died through the transgression of the one man, how much more did the grace of God and the gift by the grace of the one man Jesus Christ multiply to the many!

For if, by the transgression of the one man, death reigned through the one, how much more will those who receive the abundance of grace and of the gift of righteousness reign in life through the one, Jesus Christ!

For just as through the disobedience of the one man many were made sinners, so also through the obedience of one man many will be made righteous.

We know that our old man was crucified with him so that the body of sin would no longer dominate us, so that we would no longer be enslaved to sin.

So then, if she is joined to another man while her husband is alive, she will be called an adulteress. But if her husband dies, she is free from that law, and if she is joined to another man, she is not an adulteress.

Wretched man that I am! Who will rescue me from this body of death?

Not only that, but when Rebekah had conceived children by one man, our ancestor Isaac --

But the man who doubts is condemned if he eats, because he does not do so from faith, and whatever is not from faith is sin.
