1 Thessalonians 1:7-8; 1 Thessalonians 4:18

7 So that ye were ensamples to all that believe in Macedonia and Achaia. 8 For from you sounded out the word of the Lord not only in Macedonia and Achaia, but also in every place your faith to God-ward is spread abroad ; so that we need not to speak any thing.
18 Wherefore comfort one another with these words.
