Key

Key - (Easton's Bible Dictionary)

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.

Figurative: Used figuratively for power, since the key was sometimes worn on the shoulder as a sign of official authority (Isa 22-22). In the New Testament it is used several times thus figuratively: of Peter: "the keys of the kingdom of heaven" (Mt 16:19); of Christ, in Revelation, having the "keys of death and of Hades" (Re 1:18), also having "the key of David" (Re 3:7). An angel was given "the key of the pit of the abyss" (Re 9:1; 20:1). our Lord accused the teachers of the law of His day of taking away "the key of knowledge" from men, that is, locking the doors of truth against them (Lu 11:52; compare Mt 23:13).
