1 Thessalonians 3:1-5

Therefore when we could endure it no longer, we thought it best to be left behind at Athens alone, and we sent Timothy, our brother and God’s fellow worker in the gospel of Christ, to strengthen and encourage you as to your faith, so that no one would be disturbed by these afflictions; for you yourselves know that we have been destined for this. For indeed when we were with you, we kept telling you in advance that we were going to suffer affliction; and so it came to pass, as you know. For this reason, when I could endure it no longer, I also sent to find out about your faith, for fear that the tempter might have tempted you, and our labor would be in vain.
