1 Thessalonians 2:3-6

3For our exhortation was not from deceit, nor from uncleanness, nor in guile: 4But as we were allowed by God to be put in trust with the gospel, even so we speak; not as pleasing men, but God, who trieth our hearts. 5For neither at any time used we flattering words, as ye know, nor a cloke of covetousness; God is witness: 6Nor from men sought we glory, neither from you, nor yet from others, when we might have been burdensome, as the apostles of Christ.1
