1 Corinthians 16:15-17

15You 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, 16to submit to such people and to everyone who joins in the work and labors at it. 17I was glad when Stephanas, Fortunatus and Achaicus arrived, because they have supplied what was lacking from you.
