Albert Barnes Commentary Philippians 2:23

"Him therefore I hope to send forthwith, so soon as I shall see how it will go with me:" — Philippians 2:23 (ASV)

So soon as I shall see how it will go with me. Paul was a prisoner at Rome, and there was not a little uncertainty whether he would be condemned or acquitted. He was, it is commonly supposed, in fact released on the first trial (2 Timothy 4:16). He now felt that he would soon be able to send Timothy to them at any rate. If he was condemned and put to death, he would, of course, have no further occasion for his services; and if he were released from his present troubles and dangers, he could spare him for a season to go and visit the churches.

The words "with me" mean "to see through my own affairs."
