The order of Phi 1:16, Phi 1:17, is reversed in the best texts. Of contentions (ἐξ ἐριθείας). See on strife, Jam 3:14. Rev., better, faction. Compare Chaucer:
“For mine entente is not but for to winne
And nothing for correction of sinne”
“Pardonere's Tale,” 12337-8.
Sincerely (ἁγνῶς)
Purely, with unmixed motives. The adjective ἁγνός means pure, in the sense of chaste, free from admixture of evil, and is once applied to God, 1Jo 3:3. See on Act 26:10, footnote. Not sincerely is explained by in pretense, Phi 1:18.
To add affliction (θλῖψιν ἐπιφέρειν)
Lit., to bring affliction to bear. But the correct reading is ἐγείρειν to raise up, as Rev.: to waken or stir up affliction. The phrase is striking in the light of the original meaning of θλίψις, namely, pressure. They would make his bonds press more heavily and gall him. See on Mat 13:21.
