Charles Ellicott Commentary Mark 5:2

"And when he was come out of the boat, straightway there met him out of the tombs a man with an unclean spirit," — Mark 5:2 (ASV)

A man with an unclean spirit.—The phrase, though not peculiar to Saint Mark, is often used by him where the other Gospels have “possessed with demons, or devils.” Saint Mark and Saint Luke, it will be noticed, speak of one only; Saint Matthew of two.
