Luke 24:18

Cleopas - The same as Alpheus, father of the Apostle James, Mark 3:18 , and husband of the sister of the virgin. John 19:25 .

Art thou only a stranger - As if he had said, What has been done it Jerusalem, within these few days, has been so public, so awful, and so universally known, that, if thou hadst been but a lodger in the city for a single night, I cannot conceive how thou couldst miss hearing of these things: indeed, thou appearest to be the only person unacquainted with them.
