STOUT; STOUTNESS

stout, stout'-nes: In modern English the word signifies strength firmness, corpulence, etc., but in English Versions of the Bible (Psalms 76:5; Isaiah 10:12; 46:12; Daniel 7:20; Malachi 3:13 with stoutness" in Isaiah 9:9) it always means "bold" or "proud" and invariably in a bad sense; compare the German stolz, with which "stout" is allied.
