1 Thessalonians 3:3-5 RSV

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.
