John Gill Commentary Acts 19:41

"And when he had thus spoken, he dismissed the assembly." — Acts 19:41 (ASV)

And when he had thus spoken
Or delivered this oration, made use of the above arguments, reasonings, and expostulations:

he dismissed the assembly
he ordered them to break up, and every one to return home in peace, and go about his own business; and thus Paul, and his companions, were delivered from an imminent danger they were exposed to.
