Madness: This word is used in its proper sense in Deuteronomy 28:34, John 10:20,1 Cor. 14:23. It also denotes a reckless state of mind arising from various causes, as over-study (Ecclesiastes 1:17; 2:12), blind rage (Luke 6:11), or a depraved temper (Ecclesiastes 7:25; 9:3; 2 Peter 2:16). David feigned madness (1 Samuel 21:13) at Gath because he "was sore afraid of Achish."
