Violence covereth the mouth of the wicked - As blessings shall be on the head of the just, so the violence of the wicked shall cover their face with shame and confusion. Their own violent dealings shall be visited upon them. The mouth forsoth of unpitious men wickidnesse covereth. - Old MS. Bible. "The forehead of the ungodly is past shame, and presumptuous." - Coverdale.
Covereth - The meaning is perhaps, the violence which the wicked has done is as a bandage over his mouth, reducing him to a silence and shame, like that of the leper Leviticus 13:45; Micah 3:7 or the condemned criminal Esther 7:8, whose “face is covered.”
