1 Thessalonians 3:5

For this cause I also, when I couldn’t stand it any longer, sent that I might know your faith, for fear that by any means the tempter had tempted you, and our labor would have been in vain.

For this cause, when I could no longer forbear, I sent to know your faith, lest by some means the tempter have tempted you, and our labour be in vain.
