Exodus 3:1-5
1. Now Moses kept the flock of Jethro his father-in-law, the priest of Midian: and he led the flock to the back-side of the desert, and came to the mountain of God, even, to Horeb.
2. And the Angel of the Lord appeared unto him in a flame of fire out of the midst of a bush; and he looked, and, behold, the bush burned with fire, and the bush was not consumed.
3. And Moses said, I will now turn aside, and see this great sight, why the bush is not burnt.
4. And when the Lord saw that he turned aside to see, God called unto him out of the midst of the bush, and said, Moses, Moses. And he said, Here am I.
5. And he said, Draw not nigh hither: put off thy shoes from off thy feet; for the place whereon thou standest is holy ground.
1. Now Moses kept the flock. We have already said that he was occupied as a shepherd for a long time (viz., about forty years) before this vision appeared to him. The patience, then, of the holy man is commended by his continuance in this work; not that Moses had any intention of boastfully celebrating his own virtues, but that the Holy Spirit dictated what would be useful to us, and, as it were, suggested it to his mouth, that what he did and suffered might be an example for ever. For he must have had much mental struggle at this tedious delay, when old age, which weakens the body, came on, since even in those days few retained their activity after their eightieth year; and although he might have lived frugally, yet temperance could not protect even the most robust body against so many hardships, because it is given to very few persons to be able thus to live in the open air, and to bear heat, and cold, and hunger, constant fatigue, the care of cattle, and other troubles. God, indeed, miraculously supported the holy man in the performance of his arduous duties; but still the internal conflict must have gone on, — why does God so long delay and suspend what he so long ago determined? It was, then, no ordinary virtue which overcame these distracting assaults, which were constantly renewing his anxiety; whilst, in the mean time, he was living poorly, in huts and sheds, as well as often wandering over rough and desert places, though from childhood to mature manhood he had been accustomed to luxury; as he here relates, that, having led his flock across the Desert, he came to Horeb, which certainly could not have been effected without his experiencing the cold as he lay on the ground by night, and burning heat by day. The title of “the mountain of God” refers1 by anticipation to a future period, when the place was consecrated by the promulgation of the Law there. It is well known that Horeb is the same mountain which is also called Sinai, except that a different name is given to its opposite sides, and, properly speaking, its eastern side is called Sinai, its western, Horeb.2 Since, then, God appeared there and gave so many manifest signs of his heavenly glory, when he renewed his covenant with his people, and furnished them with a rule of perfect holiness, the place became invested with peculiar dignity.
2. And the Angel of the Lord appeared unto him. It was necessary that he should assume a visible form, that he might be seen by Moses, not as he was in his essence, but as the infirmity of the human mind could comprehend him. For thus we must believe that God, as often as he appeared of old to the holy patriarchs, descended in some way from his majesty, that he might reveal himself as far as was useful, and as far as their comprehension would admit. The same, too, is to be said of angels, who, although they are invisible spirits, yet when it seemed good to the Almighty, assumed some form in which they might be seen. But let us inquire who this Angel was? since soon afterwards he not only calls himself Jehovah, but claims the glory of the eternal and only God. Now, although this is an allowable manner of speaking, because the angels transfer to themselves the person and titles of God, when they are performing the commissions entrusted to them by him; and although it is plain from many passages, and3 especially from the first chapter of Zechariah, that there is one head and chief of the angels who commands the others, the ancient teachers of the Church have rightly understood that the Eternal Son of God is so called in respect to his office as Mediator, which he figuratively bore from the beginning, although he really took it upon him only at his Incarnation. And Paul sufficiently expounds this mystery to us, when he plainly asserts that Christ was the leader of his people in the Desert. (1 Corinthians 10:4.) Therefore, although at that time, properly speaking, he was not yet the messenger of his Father, still his predestinated appointment to the office even then had this effect, that he manifested himself to the patriarchs, and was known in this character. Nor, indeed, had the saints ever any communication with God except through the promised Mediator. It is not then to be wondered at, if the Eternal Word of God, of one Godhead and essence with the Father, assumed the name of “the Angel” on the ground of his future mission. There is a great variety of opinions as to the vision. It is too forced an allegory to make, as some do, the body of Christ of the bush, because his heavenly majesty consumed it not when he chose to inhabit it. It is also improperly wrested by those who refer it to the stubborn spirit of the nation, because the Israelites were like thorns, which yield not to the flames. But when the natural sense is set forth, it will not be necessary to refute those which are improbable. This vision is very similar to that former one which Abraham saw. (Genesis 15:17.) He saw a burning lamp in the midst of a smoking furnace; and the reason assigned is, that God will not permit his people to be extinguished in darkness. The same similitude answers to the bush retaining its entireness in the midst of the flame. The bush is likened to the humble and despised people; their tyrannical oppression is not unlike the fire which would have consumed them, had not God miraculously interposed. Thus, by the presence of God, the bush escaped safely from the fire; as it is said in Psalm 46:1, that though the waves of trouble beat against the Church and threaten her destruction, yet “shall she not be moved,” for “God is in the midst of her.” Thus was the cruelly afflicted people aptly represented, who, though surrounded by flames, and feeling their heat, yet remained unconsumed, because they were guarded by the present help of God.
