1 Thessalonians 2:4-8

but as we were allowed of God to be put in trust with the gospel, even so we speak; not as pleasing men, but God, which trieth our hearts. For neither at any time used we flattering words, as ye know, nor a cloak of covetousness; God is witness: nor of men sought we glory, neither of you, nor yet of others, when we might have been burdensome, as the apostles of Christ. But we were gentle among you, even as a nurse cherisheth her children: so being affectionately desirous of you, we were willing to have imparted unto you, not the gospel of God only, but also our own souls, because ye were dear unto us.
