Each, Each man, Each one

[ 1,,G1538, hekastos ]
each" or "every," is used of any number separately, either
(a) as an adjective qualifying a noun, e.g., Luke 6:44; John 19:23; Hebrews 3:13, where "day by day," is, lit., "according to each day;" or, more emphatically with heis, "one," in Matthew 26:22; Luke 4:40; Luke 16:5; Acts 2:3, Acts 2:6; Acts 20:31; 1 Corinthians 12:18; Ephesians 4:7, Ephesians 4:16, RV, "each (several)," for AV, "every;" Colossians 4:6; 1 Thessalonians 2:11; 2 Thessalonians 1:3;
(b) as a distributive pronoun, e.g., Acts 4:35; Romans 2:6; Galatians 6:4; in Philippians 2:4, it is used in the plural; some mss. have it thus in Revelation 6:11. The repetition in Hebrews 8:11 is noticeable, "every man" (i.e., everyone). Prefixed by the preposition ana, "apiece" (a colloquialism), it is used, with stress on the individuality, in Revelation 21:21, of the gates of the heavenly city, "each one of the several," RV; in Ephesians 5:33, preceded by kath' hena, "by one," it signifies "each (one) his own." The phrase hen kath' hen, lit., "one by one," is used in Revelation 4:8, "each one of them."
