Robertson's Word Pictures (NT)
Dost thou alone sojourn? (su monov paroikeis). Monov is predicate adjective. "Hast thou been dwelling alone (all by thyself)?" 
And not know? (kai ouk egnws). Second aorist active indicative and difficult to put into English as the aorist often is. The verb paroikew means to dwell beside one, then as a stranger like paroikoi (Ephesians 2:19). In Jerusalem everybody was talking about Jesus.
