1 Thessalonians 3:2; 1 Thessalonians 3:5

2 And sent Timotheus, our brother, and minister of God, and our fellowlabourer in the gospel of Christ, to establish you, and to comfort you concerning your faith:
5 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.
