Luke 1:12

He was troubled. — It lies in the nature of the case that during all the long years of Zachariah’s ministration, he had seen no such manifestation. As far as we may reason from the analogy of other angelic appearances, the outward form was that of a “young man clothed in white linen,” or in “bright apparel” (Matthew 28:3; Mark 16:5) — a kind of transfigured Levite, as One greater than the angels, when he manifested himself amid the imagery of the Temple, appeared as in the garments of a glorified priesthood (Revelation 1:13).
