1 Thessalonians 3:1-5 NIV

[1] So when we could stand it no longer, we thought it best to be left by ourselves in Athens. [2] We sent Timothy, who is our brother and co-worker in God’s service in spreading the gospel of Christ, to strengthen and encourage you in your faith, [3] so that no one would be unsettled by these trials. For you know quite well that we are destined for them. [4] In fact, when we were with you, we kept telling you that we would be persecuted. And it turned out that way, as you well know. [5] For this reason, when I could stand it no longer, I sent to find out about your faith. I was afraid that in some way the tempter had tempted you and that our labors might have been in vain.
