Albert Barnes Commentary Philippians 2:28

"I have sent him therefore the more diligently, that, when ye see him again, ye may rejoice, and that I may be the less sorrowful." — Philippians 2:28 (ASV)

I sent him therefore the more carefully. With more diligence, or speed; I was the more ready to send him.

That I may be the less sorrowful. That is, on account of my concern for you; that I may know that your minds are at ease, and that you rejoice in his being among you.
