1 Corinthians 16:15-17

You know that the household of Stephanas were the first converts in Achaia, and they have devoted themselves to the service of the Lord’s people. I urge you, brothers and sisters, to submit to such people and to everyone who joins in the work and labors at it. I was glad when Stephanas, Fortunatus and Achaicus arrived, because they have supplied what was lacking from you.
