1 Thessalonians 3:3-5

3that no one might be moved by these afflictions. (For yourselves know that we are set for this;

4for also, when we were with you, we told you beforehand we are about to be in tribulation, even as also it came to pass, and ye know.)

5For this reason I also, no longer able to refrain myself, sent to know your faith, lest perhaps the tempter had tempted you and our labour should be come to nothing.
