19. turn to my salvation—"turn out to me for, (or unto) salvation." This proclamation of Christ every way will turn out to my spiritual good. Christ, whose interests are my interests, being glorified thereby; and so the coming of His kingdom being furthered, which, when it does come, will bring completed "SALVATION" (Heb 9:28) to me and all whose "earnest expectation" (Php 1:20) is that Christ may be magnified in them. So far is their preaching from causing me, as they thought, tribulation in my bonds (Php 1:16). Paul plainly quotes and applies to himself the very words of the Septuagint (Job 13:16), "This shall turn out to my salvation," which belong to all God's people of every age, in their tribulation (compare Job 13:15).
through your prayer and the supply—The Greek intimately joins the two nouns together, by having but one preposition and one article: "Through your prayer and (the consequent) supply of the Spirit of Jesus Christ (obtained for me through your prayer)."
