4. DcG, verss. (except d e vg), add υμιν to παραγγελλομεν (cf. 2Th 3:2).
The double form of ποιεω has occasioned a crop of various readings:
(a) ποιειτε και ποιησετε, in א*A de; (b) ποιειτε και ποιησατε, D*gr;
(c) και ποιειτε και ποιησετε, אcDcKLP &c., f vg et facitis et facietis;
(d) και εποιησατε και ποιειτε και ποιησετε, B; cop fecistis et facitis;
(e) και εποιησατε alone, Ggr, several minn.; g et fecistis et facietis.
The early (itacistic) corruption of ποιησετε into ποιησατε (D) appears to have bewildered the copyists. Is it not just possible, however, that BG cop have preserved a true reading, and that in (a) ποιειτε was an assimilation of και εποιησατε to 2Th 3:1 above, and to 1Th 4:10? εποιησατε is commended by its difficulty (after πεποιθαμεν), and by the fact that its priority might best explain the genesis of the other readings. The initial και of B and G seems original.
