'Man's' in the Bible

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

And I saw all labour, and all success of work, that it is man's jealousy of his neighbour. This also is vanity and pursuit of the wind.

Who is as the wise? and who knoweth the explanation of things? A man's wisdom maketh his face to shine, and the boldness of his face is changed.

Whoso keepeth the commandment shall know no evil thing; and a wise man's heart knoweth time and manner.

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

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