Charles Ellicott Commentary Acts 19:36

"Seeing then that these things cannot be gainsaid, ye ought to be quiet, and to do nothing rash." — Acts 19:36 (ASV)

Seeing then that these things cannot be spoken against . . .—The language of the town-clerk has the ring of an official acceptance of the established cultus rather than of any strong personal devotion. Such language has often been heard from the defenders of institutions which were almost on the verge of ruin.

You ought to be quiet.—The verb is the same as that of the transitive “appeased” in Acts 19:35. In the exhortation to do nothing rashly we hear the voice of a worldly prudence, reminding us partly, as has been said, of Gamaliel, partly of the well-known maxim of Talleyrand, Surtout, point de zele.
