There was in the days of Herod, the king of Judea, a certain priest named Zacharias, of the priestly division of Abijah. He had a wife of the daughters of Aaron, and her name was Elizabeth.
"Actually only four divisions returned from the Exile (Ezra 2:36-39), but the four were subdivided to make up twenty-four again with the old names." [Note: Leon Morris, The Gospel According to St. Luke, p. 68.]
