A.T. Robertson Commentary Luke 2:3

"And all went to enrol themselves, every one to his own city." — Luke 2:3 (ASV)

Each to his own city (εκαστος εις την εαυτου πολιν). A number of papyri in Egypt have the heading enrolment by household (απογραφη κατ' οικιαν). Here again Luke is vindicated. Each man went to the town where his family register was kept.
