John Calvin on Philippians 4:9

9. What things ye have learned, and received, and heard By this accumulation of terms he intimates, that he was assiduous in inculcating these things. “This was my doctrine — my instruction — my discourse among you.” Hypocrites, on the other hand, insisted upon nothing but ceremonies. Now, it was a dishonorable thing to abandon the holy instruction, “C’eust este vne chose dishonneste aux Philippiens de delaisser la sainte doctrine et instruction;” — “It would have been a dishonorable thing for the Philipplans to abandon the holy doctrine and instruction.” which they had wholly imbibed, and with which they had been thorouglly imbued.

You have seen in me Now, the main thing in a public speaker “En vn prescheur;” — “In a preacher.” should be, that he may speak, not with his mouth merely, but by his life, and procure authority for his doctrine by rectitude of life. Paul, accordingly, procures authority for his exhortation on this ground, that he had, by his life no less than by his mouth, been a leader and master of virtues.

And the God of peace He had spoken of the peace of God; he now more particularly confirms what he had said, by promising that God himself, the Author of peace, will be with them. For the presence of God brings us every kind of blessing: as though he had said, that they would feel that God was present with them to make all things turn out well and prosperously, provided they apply themselves to pious and holy actions.

Philippians 4:10-14

10. But I rejoiced in the Lord greatly, that now at the last your care of me hath flourished again; wherein ye were also careful, but ye lacked opportunity.

10. Gavisu sum autem in domino valde, quod aliquando reviguistis in studio mei, de quo etiam cogitabatis, sed deerat opportunitas.

11. Not that I speak in respect of want: for I have learned, in whatsoever state I am, therewith to be content.

11. Non quod secundum penuriam loquar; ego enim didici, in quibus sum, iis contentus esse.

12. I know both how to be abased, and I know how to abound: every where and in all things I am instructed both to be full and be hungry, both to abound and to suffer need.

12. Novi et humilis esse, novi et excellere: ubique et in omnibus institutus sum, et saturari, et esurire, et abundare, et penuriam pati.

13. I can do all things through Christ which strengtheneth me.

13. Omnia possum in Christo, qui me corroborat.

14. Notwithstanding ye have well done, that ye did communicate with my affliction.

14. Caeterum benefecistis simul communicando afflictioni meae.
