Hebrews 4:12 For God's Message is full of life and power, and is keener than the sharpest two-edged sword. It pierces even to the severance of soul from spirit, and penetrates between the joints and the marrow, and it can discern the secret thoughts and purposes of the heart. (WEY)
Job 41:30 Sharpest potsherds are under him; he spreadeth a threshing-sledge upon the mire. (JPS)
