{If any one among you do err} (ean tis en humin
plan(8874)h(8869)). Third-class condition (supposed case) with ean and
the first aorist passive subjunctive of plana(935c), old verb, to go
astray, to wander ( Mt 18:12 ), figuratively ( Heb 5:2 ). {From
the truth} (apo t(8873) al(8874)heias). For truth see  1:18  3:14  Joh
8:32  1Jo 1:6  3:18f . It was easy then, and is now, to be led
astray from Christ, who is the Truth. {And one convert him} (kai
epistreps(8869) tis auton). Continuation of the third-class
condition with the first aorist active subjunctive of
epistreph(935c), old verb, to turn (transitive here as in  Lu
1:16f. , but intransitive often as  Ac 9:35 ).
