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 was released from his present troubles and dangers, he could spare him for a season to go and visit the churches.

How it will go with me - The apostle was now in captivity; his trial appears to have been approaching, and of its issue he was doubtful; though he seems to have had a general persuasion that he should be spared, see Philippians 2:19, Philippians 2:24.

Him therefore I hope to send presently,.... For the reasons now given:
so soon as I shall see how it will go with me; whether he should be released from his bonds or not; whether he should live or die; whether he should be set free, or be called to suffer martyrdom for the sake of Christ; for he expected, that the matter would be determined in a very short time, when, be it at it would, Timothy would be spared.

so soon as I shall see--that is, so soon as I shall have known for certain.
