1 Thessalonians 2:7-9 NKJV
(7) But we were gentle among you, just as a nursing mother cherishes her own children. (8) So, affectionately longing 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 dear to us. (9) For you remember, brethren, our labor and toil; for laboring night and day, that we might not be a burden to any of you, we preached to you the gospel of God.
