He will guard the feet of his faithful servants, but the wicked will be silenced in the place of darkness. "It is not by strength that one prevails;" (NIV)
He will guard the feet of His godly ones, but the wicked shall be silenced and perish in darkness; for by strength shall no man prevail. (AMP)
He will keep the feet of his saints, and the wicked shall be silent in darkness; for by strength shall no man prevail. (KJV)
