1 Thessalonians 2:7-9

But we behaved gently when we were among you, like a devoted mother tenderly caring for her own children. Having such a deep affection for you, we were delighted to share with you not only God’s good news but also our own lives, because you had become so very dear to us. For you remember, believers, our labor and hardship. We worked night and day [practicing our trade] in order not to be a [financial] burden to any of you while we proclaimed the gospel of God to you.
