Ministry of Apollos
24 Now there came to Ephesus a Jew named Apollos, a native of Alexandria. He was an eloquent man, well-versed in the scriptures. 25 He had been instructed in the Way of the Lord; and he spoke with burning enthusiasm and taught accurately the things concerning Jesus, though he knew only the baptism of John.
