1 Thessalonians 3:4-5

Twentieth_Century(i) 4 For, even while we were with you, we warned you beforehand that we were certain to encounter trouble. And so it proved, as you know. 5 Therefore, since I could no longer endure the uncertainty, I sent to make inquiries about your faith, fearing that the Tempter had tempted you, and that our toil might prove to have been in vain.
