1 Thessalonians 3:3-5

Haweis(i) 3 that no man might be shaken by these tribulations; for ye yourselves know that thereunto we are appointed. 4 For when we were with you, we told you before that we were about to suffer tribulation; as also it came to pass, and ye know. 5 For this cause also, when I could no longer forbear, I sent to know your fidelity, lest by any means the tempter had tempted you, and our labour should be in vain.
