1 Thessalonians 3:5 in the King James Version
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.
Context
4 For most certainly, when we were with you, we told you beforehand that we are to suffer affliction, even as it happened, and you know.
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.
6 But Timothy has just now come to us from you, and brought us glad news of your faith and love, and that you have good memories of us always, longing to see us, even as we also long to see you.
