'Fools' in the Bible

Keep thy feet when thou goest unto a house of God, and draw near to hear rather than to give of fools the sacrifice, for they do not know they do evil.

When thou vowest a vow to God, delay not to complete it, for there is no pleasure in fools; that which thou vowest -- complete.

The heart of the wise is in a house of mourning, And the heart of fools in a house of mirth.

Better to hear a rebuke of a wise man, Than for a man to hear a song of fools,

Be not hasty in thy spirit to be angry, For anger in the bosom of fools resteth.

The words of the wise in quiet are heard, More than the cry of a ruler over fools.
