Notes on The Holy Gospel of Jesus Christ, According to St. Luke (Author Bishop Richard Challoner (ed.))
2:7 Her first born: The meaning is, not that she had afterward any other child; but it is a way of speech among the Hebrews, to call them also the firstborn, who are the only children. See annotation Matt. 1.25.
