 Key
    frequently mentioned in Scripture. It is called in Hebrew
    _maphteah_, i.e., the opener (Judg. 3:25); and in the Greek New
    Testament _kleis_, from its use in shutting (Matt. 16:19; Luke
    11:52; Rev. 1:18, etc.). Figures of ancient Egyptian keys are
    frequently found on the monuments, also of Assyrian locks and
    keys of wood, and of a large size (comp. Isa. 22:22).
      The word is used figuratively of power or authority or office
    (Isa. 22:22; Rev. 3:7; Rev. 1:8; comp. 9:1; 20:1; comp. also
    Matt. 16:19; 18:18). The "key of knowledge" (Luke 11:52; comp.
    Matt. 23:13) is the means of attaining the knowledge regarding
    the kingdom of God. The "power of the keys" is a phrase in
    general use to denote the extent of ecclesiastical authority.
