FOOL
Any person who does not act wisely, that is, does not follow the warnings and requirements of God, which are founded in infinite wisdom. Hence "a fool" is put for a wicked man, an enemy or neglecter of God, Psalms 14:1; Proverbs 19:1. So folly is put for wickedness, 2 Samuel 13:12, 2 Samuel 1:13; Psalms 38:5, foolish lusts for wicked lusts, etc. Foolish talking, foolish questions, are vain, empty, unprofitable conversation, 2 Timothy 2:23.
