LXX Job 13:16
14 while I may take my flesh in my teeth, and put my life in my hand. 15 Though the Mighty One should lay hand upon me, forasmuch as he has begun, verily I will speak, and plead before him. 16 And this shall turn to me for salvation; for fraud shall have no entrance before him. 17 Hear, hear ye my words, for I will declare in your hearing. 18 Behold, I am near my judgment: I know that I shall appear evidently just. 19 For who is he that shall plead with me, that I should now be silent, and expire?
Philippians 1:19
17 The former proclaim Christ from selfish ambition, not sincerely, because they think they can cause trouble for me in my imprisonment. 18 What is the result? Only that in every way, whether in pretense or in truth, Christ is being proclaimed, and in this I rejoice.Yes, and I will continue to rejoice, 19 for I know that this will turn out for my deliverance through your prayers and the help of the Spirit of Jesus Christ. 20 My confident hope is that I will in no way be ashamed but that with complete boldness, even now as always, Christ will be exalted in my body, whether I live or die.
Notes and References
"... In the course of framing an apologia for his own current imprisonment (compare 1:7, 12-14), Paul echoes a fragment of voice from Job. Despite his chains, he assures the Philippians that "through your prayers and the help of the Spirit of Jesus Christ this will turn out for my deliverance" (1:19). The last part of this statement (touto moi apobesetai eis soterian), though prefaced by no quotation formula, is a verbatim citation of words lifted from Job 13:16 (LXX) ..."

"... Unless one refers specifically to the LXX text, it is easy to miss the Old Testament allusion in Paul’s statement, “What has happened to me will turn out for my deliverance”. The Greek here is touto moi apobēsetai eis sōtērian (“this will lead to salvation for me”), which reproduces Job 13:16 LXX verbatim ..."
