1 Thessalonians 3:1-5 RSV

1 Therefore when we could bear it no longer, we were willing to be left behind at Athens alone,
2 and we sent Timothy, our brother and God's servant in the gospel of Christ, to establish you in your faith and to exhort you,
3 that no one be moved by these afflictions. You yourselves know that this is to be our lot.
4 For when we were with you, we told you beforehand that we were to suffer affliction; just as it has come to pass, and as you know.
5 For this reason, when I could bear it no longer, I sent that I might know your faith, for fear that somehow the tempter had tempted you and that our labor would be in vain.
