'Man's' in the Bible

The wise man's eyes are in his head; but the fool walketh in darkness: and I myself perceived also that one event happeneth to them all.

I saw that all labor and all skillful work is due to a man’s jealousy of his friend. This too is futile and a pursuit of the wind.

All man’s labor is for his stomach,yet the appetite is never satisfied.

Who is as the wise man? and who knoweth the interpretation of a thing? a man's wisdom maketh his face to shine, and the boldness of his face shall be changed.

Whoso keepeth the commandment shall feel no evil thing: and a wise man's heart discerneth both time and judgment.

For every activity there is a right time and procedure, even though man’s troubles are heavy on him.

No man has authority over the wind, to keep the wind; or is ruler over the day of his death. In war no man's time is free, and evil will not keep the sinner safe.

All this I have seen while applying my mind to every deed that is done under the sun. There is a time in which one man has exercised power over others to their detriment.

Then said I, Wisdom is better than strength: nevertheless the poor man's wisdom is despised, and his words are not heard.

A wise man's heart is at his right hand; but a fool's heart at his left.

The words of a wise man's mouth are gracious; but the lips of a fool will swallow up himself.

Indeed, if a man should live many years, let him rejoice in them all, and let him remember the days of darkness, for they will be many. Everything that is to come will be futility.

then man's dust will go back to the earth, returning to what it was, and the spirit will return to the God who gave it.
