And there appeared to him an angel of the Lord, standing on the right side of the alter of incense.

“It is well said that there appeared an angel to Zacharias, who suddenly beheld him; and this is the expression especially used by Divine Scripture with respect to angels or God, that what cannot be seen beforehand may be said to appear. For things which are the objects of our senses are not seen as He is seen, Who is seen only as He will, and Whose nature is not to be seen.”

“And there appeared unto him an angel of the Lord,.... Gabriel, as seem's manifest from Luk 1:19 the same angel that had appeared to Daniel, about the time of the evening oblation, near five hundred years before, and gave him an account of the time of the Messiah's coming, Dan 9:21. The Jews sometimes speak of divine and wonderful appearances to their priests, at such times, and in such places: "it is a tradition that R. Ishmael ben Elishah should say, one time I went in, , "to burn incense": and I saw Actariel (one of the names of God with them) the Lord, the Lord of hosts, who was sitting on a throne, high and lifted up. (m). And so they say of Simeon the just, that there was always an appearance when he went into the holy of holies; it is related thus (n): "Simeon the just, ministered unto Israel in the high priesthood, forty years; and in the last year, he said to them, I shall die this year: they said to him, from whence dost thou know it? He replied to them, every year that I have entered into the holy of holies, there was, , "one old man" clothed in white, and veiled in white, that went in with me, and came out with me; and this year he went in with me, but did not come out with me. And according to Josephus (o), the high priest Hyrcanus received an oracle, or answer from God, as he was offering incense; so that the Jews ought not to discredit such an appearance to Zacharias: standing on the right side of the altar of incense; of which, see Exo 30:1 the situation of it, according to the Jews, was this (p): "the table (of showbread) was in the north, two cubits and a half distant from the wall; and the candlestick was in the south, two cubits and a half distant from the wall; and the altar (of incense) was in the middle, and stood between them. And to "this agrees the account of Maimonides (q), who says, the candlestick was on the south, on the left hand, as you go in; and the table of shewbread on the right hand, and both of them on the side of the holy of holies without; and the altar of incense was between them both without. So that it was on the north side that the angel stood, (m) T. Bab. Berncot, fol. 7. 1. (n) T. Hieros. Yoma, fol. 42. 3. (o) De Bello Jud. l. 13. c. 18. (p) T. Bab. Yoma, fol. 33. 2. (q) Hilch. Beth Habbechira, c. 1. sect. 7.”

“There appeared - an angel of the Lord - There had been neither prophecy nor angelic ministry vouchsafed to this people for about 400 years. But now, as the Sun of righteousness is about to arise upon them, the day-spring from on high visits them, that they may be prepared for that kingdom of God which was at hand. Every circumstance here is worthy of remark: 1. That an angel should now appear, as such a favor had not been granted for 400 years. 2. The person to whom this angel was sent - one of the priests. The sacerdotal office itself pointed out the Son of God till he came: by him it was to be completed, and in him it was to be eternally established: - Thou art a priest for ever, Psa 110:4. 3. The place in which the angel appeared - Jerusalem; out of which the word of the Lord should go forth, Isa 2:3, and not at Hebron, in the hill country of Judea, where Zacharias lived, Luk 1:39, which was the ordinary residence of the priests, Jos 21:11, where there could have been few witnesses of this interposition of God, and the effects produced by it. 4. The place where he was when the angel appeared to him - in the temple, which was the place where God was to be sought; the place of his residence, and a type of the human nature of the blessed Jesus, Joh 2:21. 5. The time in which this was done - the solemn hour of public prayer. God has always promised to be present with those who call upon him. When the people and the priest go hand in hand, and heart with heart, to the house of God, the angel of his presence shall surely accompany them, and God shall appear among them. 6. The employment of Zacharias when the angel appeared - he was burning incense, one of the most sacred and mysterious functions of the Levitical priesthood, and which typified the intercession of Christ: confer Heb 7:25, with Heb 9:24. 7. The long continued and publicly known dumbness of the priest, who doubted the word thus miraculously sent to him from the Lord: a solemn intimation of what God would do to all those who would not believe in the Lord Jesus. Every mouth shall be stopped.”
