Acts 8:7

For unclean spirits
Devils, so called because they were unclean themselves, defiled others, add 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.
