1 Thessalonians 1:9; 1 Thessalonians 4:13

9 For they themselves report about us what kind of a reception we had with you, and how you turned to God from idols to serve a living and true God,
13 But we do not want you to be uninformed, brethren, about those who are asleep, so that you will not grieve as do the rest who have no hope.
