That your glorying. The expression which he employs, en emoi, I have rendered de me (as to me,) because the preposition is made use of twice, but in different senses. No one assuredly will deny that I have faithfully brought out Paul's mind. The rendering given by some -- per Christum, (through Christ,) I do not approve of. For in Christ is employed in place of Secundum Christum, (According to Christ,) or Christiane, (Christianly,) to intimate that it was a holy kind of glorying. For otherwise we are commanded to glory in God alone. (1-Corinthians 1:31.) Hence malevolent persons might meet Paul with the objection, How is it allowable for the Philippians to glory as to thee? He anticipates this calumny by saying that they will do this according to Christ -- glorying in a servant of Christ, with a view to the glory of his Lord, and that with an eye to the doctrine rather than to the individual, and in opposition to the false apostles, just as David, by comparing himself with hypocrites, boasts of his righteousness. (Psalm 7:8.)

That your rejoicing may be more abundant in Jesus Christ - Through the mercy and grace of Christ, If he was spared, his deliverance would be traced to Christ, and they would rejoice together in one who had so mercifully delivered him.
For me by my coming to you again - Their joy would not only be that he was delivered, but that he was permitted to see them again.

That your rejoicing may be more abundant - Men rejoice more in recovering a thing that was lost, than they do in a continual possession of what is of much greater value.

That your rejoicing may be more abundant,.... They had rejoiced greatly on his account already, blessing God that ever they had seen his face, or heard his voice; as they had great reason to do, he being the happy instrument of first bringing the Gospel to them, and of their conversion; and now he hoped he should be delivered out of prison, and see them again, that their joy might be increased and abound yet more and more, upon his deliverance, they had so earnestly prayed and so much longed for, and at the sight of him they so dearly loved: and yet to show that this their joy was not looked upon by him as a carnal one, or as arising from a natural affection, he observes that it was
in Jesus Christ; though they rejoiced in him as an instrument, and therefore he adds,
for me; yet it was on account of Jesus Christ, the subject of his ministry; their joy did not centre in the apostle, but had Christ for its object, whose person, righteousness, and salvation were held forth by him to their view and comfort; and though they would still more and more rejoice should he return to them once more,
by my coming to you again; yet still it would he in Christ, and because of the fulness of the blessing of the Gospel of Christ, in which he should come to them.

Translate, "That your matter of glorying (or rejoicing) may abound in Christ Jesus in me (that is, in my case; in respect to me, or for me who have been granted to your prayers, Philippians 1:19) through my presence again among you." ALFORD makes the "matter of glorying," the possession of the Gospel, received from Paul, which would abound, be assured and increased, by his presence among them; thus, "in me," implies that Paul is the worker of the material of abounding in Christ Jesus. But "my rejoicing over you" (Philippians 2:16), answers plainly to "your rejoicing in respect to me" here.
