John Gill Commentary Acts 8:7

"For [from] many of those that had unclean spirits, they came out, crying with a loud voice: and many that were palsied, and that were lame, were healed." — Acts 8:7 (ASV)

For unclean spirits
Devils, so called because they were unclean themselves, defiled others, and delighted in impure persons and places; (See Gill on Matthew 10:1)

crying with loud voice ;
showing their unwillingness to remove, and the irresistibleness of divine power they could not withstand:

came out of many that were possessed
with them; who had for a long time dwelt in them, and had greatly afflicted them:

and many taken with palsies, and that were lame, were healed ;
by Philip, in the name of Christ, through a word speaking, or by touching them, without making use of any means or medicines.
