1 Thessalonians 2:6-9

Nor did we seek glory from people, whether from you or from others, though we could have made demands as apostles of Christ. But we were gentle among you, like a nursing mother taking care of her own children. So, being affectionately desirous of you, we were ready to share with you not only the gospel of God but also our own selves, because you had become very dear to us. For you remember, brothers, our labor and toil: we worked night and day, that we might not be a burden to any of you, while we proclaimed to you the gospel of God.
