1 Thessalonians 2:9-12

For ye remember, brethren, our labour and travail: for labouring night and day, because we would not be chargeable unto any of you, we preached unto you the gospel of God. Ye [are] witnesses, and God [also], how holily and justly and unblameably we behaved ourselves among you that believe: As ye know how we exhorted and comforted and charged every one of you, as a father [doth] his children, That ye would walk worthy of God, who hath called you unto his kingdom and glory. - 1 Thessalonians 2:9-12
