John Gill Commentary Acts 5:18

"and laid hands on the apostles, and put them in public ward." — Acts 5:18 (ASV)

And laid their hands on the apostles
That is, laid hold on them, and took them, and carried them away; at least their servants did so, by their orders:

and put them in the common prison ;
where malefactors were put; and this both for greater security, and for greater disgrace.
