John Chrysostom

"Wherefore, when we could no longer forbear, we thought it good to be left behind at Athens alone. And sent Timothy, our brother and God's minister and our fellow-worker in the Gospel of Christ."

Instead of saying, "we chose." And this he says, not as extolling Timothy, but honoring them, that he sent them the fellow-worker, and minister of the Gospel. As if he had said, Having withdrawn him from his labors we have sent to you the minister of God, and our fellow-laborer in the Gospel of Christ.

"To establish you, and to comfort you concerning your faith."
