“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.”
King James Version (KJV)
1Th 3:5 Lest by some means the tempter have tempted you. The tempter is Satan. Unable to hear from them, fearing the effect of their fiery trial, he sent Timothy, not only to strengthen them, but to report to him their state.
