Madness

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