And now send men to Joppa
Which lay near to Caesarea;
and call for one Simon, whose surname is Peter:
the angel was not sent to instruct Cornelius himself, but to direct him to an apostle of Christ, and minister of the Gospel, who should do it; for not angels, but men, are employed in the ministry of the word, which is the ordinary means of spiritual knowledge, and of increasing it. So the eunuch was instructed by Philip, and Saul by Ananias; which shows the excellency and usefulness of the Gospel ministry and ministers, and what dignity is put upon them, what use should be made of them, and in what esteem they should be had.
