Charles Ellicott Commentary Acts 21:10

"And as we tarried there some days, there came down from Judaea a certain prophet, named Agabus." — Acts 21:10 (ASV)

As we tarried there many days . . .—The adjective is in the comparative degree, and implies, accordingly, a longer time than had been intended. Probably the voyage had been quicker than the travelers had expected, and there was therefore time to remain at Caesarea, and yet to arrive at Jerusalem, as St. Paul planned, in time for Pentecost (Acts 20:16). There was, at any rate, time for the news of his arrival to reach Jerusalem, and for Agabus (see Note on Acts 11:28) to come down as a result.
