The years of the life of Moses are remarkably divided into three forties: the first forty he spent as a prince in Pharaoh's court, the second a shepherd in Midian, the third a king in Jeshurun; so changeable is the life of men, especially the life of good men. He had now finished his second forty, when he received his commission to bring Israel out of Egypt. Note, Sometimes it is long before God calls his servants out of that work which of old he designed them for, and has been graciously preparing them for. Moses was born to be Israel's deliverer, and yet not a word is said of it to him till he is eighty years of age. Now obverve,

I.How this appearance of God to him found him employed. He was keeping the flock (tending sheep) near mount Horeb, Exo 3:1. This was a poor employment for a man of his parts and education, yet he rests satisfied with it, and thus learns meekness and contentment to a high degree, for which he is more celebrated in sacred writ than for all his other learning. Note, 1. In the calling to which we are called we should abide, and not be given to change. 2. Even those that are qualified for great employments and services must not think it strange if they be confined to obscurity; it was the lot of Moses before them, who foresaw nothing to the contrary but that he should die, as he had lived a great while, a poor despicable shepherd. Let those that think themselves buried alive be content to shine like lamps in their sepulchres, and wait till God's time come for setting them on a candlestick. Thus employed Moses was, when he was honoured with this vision. Note, (1.) God will encourage industry. The shepherds were keeping their flocks when they received the tidings of our Saviour's birth, Luk 2:8. Satan loves to find us idle; God is well pleased when he find us employed. (2.) Retirement is a good friend to our communion with God. When we are alone, the Father is with us. Moses saw more of God in a desert than ever he had seen in Pharaoh's court.

II.What the appearance was. To his great surprise he saw a bush burning, when he perceived no fire either from earth or heaven to kindle it, and, which was more strange, it did not consume, Exo 3:2. It was an angel of the Lord that appeared to him; some think, a created angel, who speaks in the language of him that sent him; others, the second person, the angel of the covenant, who is himself Jehovah. It was an extraordinary manifestation of the divine presence and glory; what was visible was produced by the ministry of an angel, but he heard God in it speaking to him. 1. He saw a flame of fire; for our God is a consuming fire. When Israel's deliverance out of Egypt was promised to Abraham, he saw a burning lamp, which signified the light of joy which that deliverance should cause (Gen 15:17); but now it shines brighter, as a flame of fire, for God in that deliverance brought terror and destruction to his enemies, light and heat to his people, and displayed his glory before all. See Isa 10:17. 2. This fire was not in a tall and stately cedar, but in a bush, a thorny bush, so the word signifies; for God chooses the weak and despised things of the world (such as Moses, now a poor shepherd), with them to confound the wise; he delights to beautify and crown the humble. 3. The bush burned, and yet was not consumed, an emblem of the church now in bondage in Egypt, burning in the brick-kilns, yet not consumed; perplexed, but not in despair; cast down, but not destroyed.

III.The curiosity Moses had to enquire into this extraordinary sight: I will turn aside and see, Exo 3:3. He speaks as one inquisitive and bold in his enquiry; whatever it was, he would, if possible, know the meaning of it. Note, Things revealed belong to us, and we ought diligently to enquire into them.

IV.The invitation he had to draw near, yet with a caution not to come too near, nor rashly.

1.God gave him a gracious call, to which he returned a ready answer, Exo 3:4. When God saw that he took notice of the burning bush, and turned aside to see it, and left his business to attend it, then God called to him. If he had carelessly neglected it as an ignis fatuus - a deceiving meteor, a thing not worth taking notice of, it is probable that God would have departed, and said nothing to him; but, when he turned aside, God called to him. Note, Those that would have communion with God must attend upon him, and approach to him, in those ordinances wherein he is pleased to manifest himself, and his power and glory, though it be in a bush; they must come to the treasure, though in an earthen vessel. Those that seek God diligently shall find him, and find him their bountiful rewarder. Draw nigh to God, and he will draw nigh to you. God called him by name, Moses, Moses. This which he heard could not but surprise him much more than what he saw. The word of the Lord always went along with the glory of the Lord, for every divine vision was designed for divine revelation, Job 4:16, etc.; Job 32:14-15. Divine calls are then effectual, (1.) When the Spirit of God makes them particular, and calls us by name. The word calls, Ho, every one! The Spirit, by the application of that, calls, Ho, such a one! I know thee by name, Exo 33:12. (2.) When we return an obedient answer to them, as Moses here, "Here am I, what saith my Lord unto his servant? Here am I, not only to hear what is said, but to do what I am bidden."

2.God gave him a needful caution against rashness and irreverence in his approach, (1.) He must keep his distance; draw near, but not too near; so near as to hear, but not so near as to pry. His conscience must be satisfied, but not his curiosity; and care must be taken that familiarity do not breed contempt. Note, In all our approaches to God, we ought to be deeply affected with the infinite distance there is between us and God, Ecc 5:2. Or this may be taken as proper to the Old Testament dispensation, which was a dispensation of darkness, bondage, and terror, from which the gospel happily frees us, giving us boldness to enter into the holiest, and inviting us to draw near. (2.) He must express his reverence, and his readiness to obey: Put off thy shoes from off thy feet, as a servant. Putting off the shoe was then what putting off the hat is now, a token of respect and submission. "The ground, for the present, is holy ground, made so by this special manifestation of the divine presence, during the continuance of which it must retain this character; therefore tread not on that ground with soiled shoes." Keep thy foot, Ecc 5:1. Note, We ought to approach to God with a solemn pause and preparation; and, though bodily exercise alone profits little, yet we ought to glorify God with our bodies, and to express our inward reverence by a grave and reverent behaviour in the worship of God, carefully avoiding everything that looks light, and rude, and unbecoming the awfulness of the service.

V.The solemn declaration God made of his name, by which he would be known to Moses: I am the God of thy father, Exo 3:6. 1. He lets him know that it is God who speaks to him, to engage his reverence and attention, his faith and obedience; for this is enough to command all these: I am the Lord. Let us always hear the word as the word of God, Th1 2:13. 2. He will be known as the God of his father, his pious father Amram, and the God of Abraham, Isaac, and Jacob, his ancestors, and the ancestors of all Israel, for whom God was now about to appear. By this God designed, (1.) To instruct Moses in the knowledge of another world, and to strengthen his belief of a future state. Thus it is interpreted by our Lord Jesus, the best expositor of scripture, who from this proves that the dead are raised, against the Sadducees. Moses, says he, showed it at the bush (Luk 20:37), that is, God there showed it to him, and in him to us, Mat 22:31, etc. Abraham was dead, and yet God is the God of Abraham; therefore Abraham's soul lives, to which God stands in relation; and, to make his soul completely happy, his body must live again in due time. This promise made unto the fathers, that God would be their God, must include a future happiness; for he never did anything for them in this world sufficient to answer to the vast extent and compass of that great word, but, having prepared for them a city, he is not ashamed to be called their God, Heb 11:16; and see Act 26:6, Act 26:7; Act 24:15. (2.) To assure Moses of the fulfillment of all those particular promises made to the fathers. He may confidently expect this, for by these words it appears that God remembered his covenant, Exo 2:24. Note, [1.] God's covenant-relation to us as our God is the best support in the worst of times, and a great encouragement to our faith in particular promises. [2.] When we are conscious to ourselves of our own great unworthiness we may take comfort from God's relation to our fathers, Ch2 20:6.

VI.The solemn impression this made upon Moses: He hid his face, as one both ashamed and afraid to look upon God. Now that he knew it was a divine light his eyes were dazzled with it; he was not afraid of a burning bush till he perceived that God was in it. Yea, though God called himself the God of his father, and a God in covenant with him, yet he was afraid. Note, 1. The more we see of God the more cause we shall see to worship him with reverence and godly fear. 2. Even the manifestations of God's grace and covenant-love should increase our humble reverence of him.

Put off thy shoes - It is likely that from this circumstance all the eastern nations have agreed to perform all the acts of their religious worship barefooted. All the Mohammedans, Brahmins, and Parsees do so still. The Jews were remarked for this in the time of Juvenal; hence he speaks of their performing their sacred rites barefooted; Sat. vi., ver. 158:

Observant ubi festa mero pede sabbata reges.

The ancient Greeks did the same. Jamblichus, in the life of Pythagoras, tells us that this was one of his maxims, Ανυποδητος θυε και προσκυνει, Offer sacrifice and worship with your shoes off. And Solinus asserts that no person was permitted to enter into the temple of Diana, in Crete, till he had taken off his shoes. "Aedem Numinis (Dianae) praeterquam nudus vestigio nulles licito ingreditur." Tertullian observes, de jejunio, that in a time of drought the worshippers of Jupiter deprecated his wrath, and prayed for rain, walking barefooted. "Cum stupet caelum, et aret annus, nudipedalia, denunciantur." It is probable that נעלים nealim, in the text, signifies sandals, translated by the Chaldee סנדל sandal, and סנדלא sandala, (see Gen 14:23), which was the same as the Roman solea, a sole alone, strapped about the foot As this sole must let in dust, gravel, and sand about the foot in travelling, and render it very uneasy, hence the custom of frequently washing the feet in those countries where these sandals were worn. Pulling off the shoes was, therefore, an emblem of laying aside the pollutions contracted by walking in the way of sin. Let those who name the Lord Jesus Christ depart from iniquity. In our western countries reverence is expressed by pulling off the hat; but how much more significant is the eastern custom! "The natives of Bengal never go into their own houses with their shoes on, nor into the houses of others, but always leave their shoes at the door. It would be a great affront not to attend to this mark of respect when visiting; and to enter a temple without pulling off the shoes would be an unpardonable offense." - Ward.

The place whereon thou standest is holy ground - It was not particularly sanctified by the Divine presence; but if we may credit Josephus, a general opinion had prevailed that God dwelt on that mountain; and hence the shepherds, considering it as sacred ground, did not dare to feed their flocks there. Moses, however, finding the soil to be rich and the pasturage good, boldly drove his flock thither to feed on it - Antiq., b. ii., c. xii., s. 1.

And he said, draw not nigh hither,.... Keep a proper distance:

put off thy shoes from off thy feet; dust and dirt cleaving to shoes, and these being ordered to be put off from the feet, the instrument of walking, show that those that draw nigh to God, and are worshippers of him, ought to be of pure and holy lives and conversations:

for the place whereon thou standest is holy ground; not that there was any inherent holiness in this spot of ground more than in any other, which ground is not capable of; but a relative holiness on account of the presence of God here at this time, and was not permanent, only while a pure and holy God was there: hence, in after times, the temple being the place of the divine residence, the priests there performed their services barefooted, nor might a common person enter into the temple with his shoes on (k); and to this day the Jews go to their synagogues barefooted on the day of atonement (l), to which Juvenal (m) seems to have respect; and from hence came the Nudipedalia among the Heathens, and that known symbol of Pythagoras (n), "sacrifice and worship with naked feet": in this manner the priests of Diana sacrificed to her among the Cretians and other people (o); and so the priests of Hercules did the same (p); the Brahmans among the Indians never go into their temples without plucking off their shoes (q); so the Ethiopian Christians, imitating Jews and Gentiles, never go into their places of public worship but with naked feet (r), and the same superstition the Turks and Mahometans observe (s).

put off thy shoes--The direction was in conformity with a usage which was well known to Moses, for the Egyptian priests observed it in their temples, and it is observed in all Eastern countries where the people take off their shoes or sandals, as we do our hats. But the Eastern idea is not precisely the same as the Western. With us, the removal of the hat is an expression of reverence for the place we enter, or rather of Him who is worshipped there. With them the removal of the shoes is a confession of personal defilement and conscious unworthiness to stand in the presence of unspotted holiness.
