γάρ,
co-ordinating particle, contr. of γε ἄρα,
verily then, hence, in truth, indeed, yea, then, why, and when giving a reason or explanation, for, the usage in NT being in general accord with that of cl.;
1. explicative and epexegetic: Mt 4:1819:12, Mk 1:165:4216:4, Lk 11:30, Ro 7:1, I Co 16:5, al.
2. Conclusive, in questions, answers and exclamations: Mt 9:527:23, Lk 9:2522:27, Jo 9:30, Ac 8:3116:3719:35, Ro 15:26, I Co 9:10, Phl 1:18 (Ellic., in l.), I Th 2:20, al.
3. Causal: Mt 1:212:2, 5, 6, 3:23, Mk 1:22, 9:6, Lk 1:15, 18, Jo 2:25, Ac 2:25, Ro 1:9, 11, I Co 11:5, Re 1:3, al.; giving the reason for a command or prohibition, Mt 2:203:9, Ro 13:11, Col 3:3, I Th 4:3, al.; where the cause is contained in an interrog. statement, Lk 22:27, Ro 3:34:3, I Co 10:29; καὶ γάρ, for also, Mk 10:45, Lk 6:32, I Co 5:7, al. id. as in cl. = etenim, where the καί loses its connective force (Bl., §78, 6; Kühner 3, ii, 854f.), Mk 14:70, Lk 1:6622:37, II Co 13:4. The proper place of γάρ is after the first word in a clause, but in poets it often comes third or fourth, and so in late prose: II Co 1:19. Yet "not the number but the nature of the word after which it stands is the point to be noticed" (v. Thayer, s.v.).
