A.T. Robertson Commentary Luke 24:18

"And one of them, named Cleopas, answering said unto him, Dost thou alone sojourn in Jerusalem and not know the things which are come to pass there in these days?" — Luke 24:18 (ASV)

Dost thou alone sojourn? (συ μονος παροικεισ; ). Μονος is predicate adjective. "Hast thou been dwelling alone (all by thyself)?"

And not know? (κα ουκ εγνωσ; ). Second aorist active indicative and difficult to put into English as the aorist often is. The verb παροικεω means to dwell beside one, then as a stranger like παροικο (Ephesians 2:19). In Jerusalem everybody was talking about Jesus.
