1. GAT Extended? Based on it.

   [Sammet 1969, p. 139].

2. A low-level digital logic component. Gates perform boolean functions (e.g. and, not), store bits of data (e.g. a flip-flop), and connect and disconnect various parts of the overall circuit to control the flow of data (tri-state buffer).

   In a cpu, the term applies particularly to the buffers that route data between the various functional units. Each gate allows data to flow from one unit to another or enables data from one output onto a certain bus.

(1.) Of cities, as of Jerusalem (Jer. 37:13; Neh. 1:3; 2:3; 3:3), of Sodom (Gen. 19:1), of Gaza (Judg. 16:3).

(2.) Of royal palaces (Neh. 2:8).

(3.) Of the temple of Solomon (1 Kings 6:34, 35; 2 Kings 18:16); of the holy place (1 Kings 6:31, 32; Ezek. 41:23, 24); of the outer courts of the temple, the beautiful gate (Acts 3:2).

(4.) Tombs (Matt. 27:60).

(5.) Prisons (Acts 12:10; 16:27).

(6.) Caverns (1 Kings 19:13).

(7.) Camps (Ex. 32:26, 27; Heb. 13:12).

The materials of which gates were made were,

(1.) Iron and brass (Ps. 107:16; Isa. 45:2; Acts 12:10).

(2.) Stones and pearls (Isa. 54:12; Rev. 21:21).

(3.) Wood (Judg. 16:3) probably.

At the gates of cities courts of justice were frequently held, and hence "judges of the gate" are spoken of (Deut. 16:18; 17:8; 21:19; 25:6, 7, etc.). At the gates prophets also frequently delivered their messages (Prov. 1:21; 8:3; Isa. 29:21; Jer. 17:19, 20; 26:10). Criminals were punished without the gates (1 Kings 21:13; Acts 7:59). By the "gates of righteousness" we are probably to understand those of the temple (Ps. 118:19). "The gates of hell" (R.V., "gates of Hades") Matt. 16:18, are generally interpreted as meaning the power of Satan, but probably they may mean the power of death, denoting that the Church of Christ shall never die.
