I Corinthians 16:15-18

¹⁵Now I urge you, brethren (you know the household of Stephanas, that they were the first fruits of Achaia, and that they have devoted themselves for ministry to the saints), ¹⁶that you also be in subjection to such men and to everyone who helps in the work and labors. ¹⁷I rejoice over the coming of Stephanas and Fortunatus and Achaicus, because they have supplied what was lacking on your part. ¹⁸For they have refreshed my spirit and yours. Therefore acknowledge such men.
