1 Thessalonians 2:6-9

nor did we seek glory from men, either from you or from others, even though as apostles of Christ we might have asserted our authority. But we proved to be gentle among you, as a nursing mother tenderly cares for her own children. Having so fond an affection for you, we were well-pleased to impart to you not only the gospel of God but also our own lives, because you had become very dear to us. For you recall, brethren, our labor and hardship, how working night and day so as not to be a burden to any of you, we proclaimed to you the gospel of God.
