1 Thessalonians 3:3-5

Worrell(i) 3 that no one should be shaken in these tribulations; for ye yourselves know that for this we are appointed. 4 For even when we were with you, we told you beforehand, "We are about to suffer tribulation"; even as also it came to pass, and ye know. 5 For this reason, I also, no longer enduring it, sent, that I might know your faith, lest by some means the tempter tempted you, and our labor should be in vain.
