16:10-12 Timothy came to do the work of the Lord. Therefore to vex his spirit, would be to grieve the Holy Spirit; to despise him, would be to despise Him that sent him. Those who work the work of the Lord, should be treated with tenderness and respect. Faithful ministers will not be jealous of each other. It becomes the ministers of the gospel to show concern for each other's reputation and usefulness.

10. Now—rather, "But." Therefore Timothy was not the bearer of the Epistle; for it would not then be said, "IF Timothy come." He must therefore have been sent by Paul from Ephesus before this Epistle was written, to accord with 1Co 4:17-19; and yet the passage here implies that Paul did not expect him to arrive at Corinth till after the letter was received. He tells them how to treat him "if" he should arrive. Ac 19:21, 22 clears up the difficulty: Timothy, when sent from Ephesus, where this Epistle was written, did not proceed direct to Corinth, but went first to Macedonia; thus though sent before the letter, he might not reach Corinth till after it was received in that city. The undesigned coincidence between the Epistle and the history, and the clearing up of the meaning of the former (which does not mention the journey to Macedonia at all) by the latter, is a sure mark of genuineness [Paley, Horæ Paulinæ]. It is not certain that Timothy actually reached Corinth; for in Ac 19:22 only Macedonia is mentioned; but it does not follow that though Macedonia was the immediate object of his mission, Corinth was not the ultimate object. The "IF Timothy come," implies uncertainty. 2Co 1:1 represents him with Paul in Macedonia; and 2Co 12:18, speaking of Titus and others sent to Corinth, does not mention Timothy, which it would have probably done, had one so closely connected with the apostle as Timothy was, stayed as his delegate at Corinth. The mission of Titus then took place, when it became uncertain whether Timothy could go forward from Macedonia to Corinth, Paul being anxious for immediate tidings of the state of the Corinthian Church. Alford argues that if so, Paul's adversaries would have charged him with fickleness in this case also (2Co 1:17), as in the case of his own change of purpose. But Titus was sent directly to Corinth, so as to arrive there before Timothy could by the route through Macedonia. Titus' presence would thus make amends for the disappointment as to the intended visit of Timothy and would disarm adversaries of a charge in this respect (2Co 7:6, 7).

without fear—Referring perhaps to a nervous timidity in Timothy's character (1Ti 3:15; 5:22, 24). His youth would add to this feeling, as well as his country, Lystra, likely to be despised in refined Corinth.
