Addicted Themselves to the Ministry

15 I beseech you, brethren, (ye know the house of Stephanas, that it is the firstfruits of Achaia, and that they have addicted themselves to the ministry of the saints,) 16 That ye submit yourselves unto such, and to every one that helpeth with us, and laboureth. 17 I am glad of the coming of Stephanas and Fortunatus and Achaicus: for that which was lacking on your part they have supplied. 18 For they have refreshed my spirit and yours: therefore acknowledge ye them that are such. 1 Corinthians 16:15-18
