Acts 18:25 - Coke's Commentary on the Holy Bible

And being fervent in the spirit,— The baptism of John, we find, ch. Acts 19:2 was attended with very imperfect instruction or divine illuminations; yet upon that baptism, and the grace he had received, Apollos, being a man of warmth and eloquence, is said to have preached the gospel ακριβως, that is, with a great deal of accuracy, study, and pains, according to the best of his light. It is very probable, that he returned to live at Alexandria soon after he had been baptized with John's baptism; and so had no opportunityof being explicitly acquainted with the doctrines of the gospel, as delivered by Christ and his apostles, till he came to Ephesus, and was taught them by these eminent Christians Aquila and Priscilla, who, in all probability, lodged in their own house, that they might the more familiarly and fully converse with him about them. See Acts 18:26.
