1041 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.; explicative and epexegetic: Mt 4:18 19:12 , Mk 1:16 5:42 16:4 , Lk 11:30 , Ro 7:1 , I Co 16:5 , al. Conclusive, in questions, answers and exclamations: Mt 9:5 27:23 , Lk 9:25 22:27 , Jo 9:30 , Ac 8:31 16:37 19:35 , Ro 15:26 , I Co 9:10 , Phl 1:18 (Ellic., in l.), I Th 2:20 , al. Causal: Mt 1:21 2:2 , 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 2:20 3:9 , Ro 13:11 , Col 3:3 , I Th 4:3 , al.; where the cause is contained in an interrog. statement, Lk 22:27 , Ro 3:3 4:3 , 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 1:66 22:37 , 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.).
