Noah Webster's Dictionary (n.) One who, or that which, covers.

Multi-Version Concordance Coverer (1 Occurrence) Isaiah 22:18 And thy coverer covering, wrapping round, Wrappeth thee round, O babbler, On a land broad of sides -- there thou diest, And there the chariots of thine honour 'Are' the shame of the house of thy lord. (YLT)
