'Man's' in the Bible

From the fruit of the mouth is one satisfied with good, And the deed of man's hands returneth to him.

The ransom of a man's life are his riches, And the poor hath not heard rebuke.

When a man's ways please Jehovah, even his enemies, He causeth to be at peace with him.

Deep waters are the words of a man's mouth, The fountain of wisdom is a flowing brook.

From the fruit of a man's mouth is his belly satisfied, From the increase of his lips he is satisfied.

Many are the purposes in a man's heart, And the counsel of Jehovah it standeth.
