Fool. This term, in Scripture, implies moral pravity. The fool is not merely an unreasonable, he is a sinful person. 2 Samuel 13:13, Psalms 14:1, Proverbs 19:1, Proverbs 19:29, Proverbs 20:3, Proverbs 1:26-5, Matthew 23:17, Romans 1:1-22. Hence the censure of one who unjustifiably cast so great a reproach upon a brother. Matthew 5:22.
