1 Thessalonians 3:3-5 NRS

3 so that no one would be shaken by these persecutions. Indeed, you yourselves know that this is what we are destined for.
4 In fact, when we were with you, we told you beforehand that we were to suffer persecution; so it turned out, as you know.
5 For this reason, when I could bear it no longer, I sent to find out about your faith; I was afraid that somehow the tempter had tempted you and that our labor had been in vain.
