'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.

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.

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.
