John Gill Commentary Luke 8:27

"And when he was come forth upon the land, there met him a certain man out of the city, who had demons; and for a long time he had worn no clothes, and abode not in [any] house, but in the tombs." — Luke 8:27 (ASV)

And when he went forth to land
The Persic and Ethiopic versions read,

when they went forth to land ;
when Christ and his disciples came out of the ship, and went ashore:

there met him out of the city a certain man ;
or rather, there met him a certain man of the city; that is, one that belonged to, and was an inhabitant of Gadera, or some city thereabout; who had been born and brought up, and had lived there; for certain it is, that he did not now come out of the city, but out of the tombs, as in (Matthew 8:28) (Mark 5:2) and to which agrees the account of him that follows here; in the Vulgate Latin version, these words, "out of the city" are omitted; which the interpreter not understanding, might leave out, as carrying in it a seeming contradiction to the accounts of him:

which had devils long time .
The Vulgate Latin, Syriac, Persic, and Arabic versions, read in the singular number, which had a devil: and which agrees with (Luke 8:29) for though more are after mentioned, yet the many might be under one head, and chief of them; but in all the copies, it is read in the plural number, "devils"; and to this agrees the name of legion, for there were many devils in him, and they had a possession of him a long time which aggravates the miserable condition of this man, and illustrates the power of Christ in freeing him from them:

and wore no clothes ;
but went naked, and when any were put upon him, would tear them in pieces:

neither abode in any house ,
but in the tombs; (See Gill on Mark 5:3).
