I.The orders given concerning the altar of incense are, 1. That it was to be made of wood, and covered with gold, pure gold, about a yard high and half a yard square, with horns at the corners, a golden cornice round it, with rings and staves of gold, for the convenience of carrying it, Exo 30:1-5. It does not appear that there was any grate to this altar for the ashes to fall into, that they might be taken away; but, when they burnt incense, a golden censer was brought with coals in it, and placed upon the altar, and in that censer the incense was burnt, and with it all the coals were taken away, so that no coals nor ashes fell upon the altar. The measure of the altar of incense in Ezekiel's temple is double to what it is here (Eze 41:22), and it is there called an altar of wood, and there is no mention of gold, to signify that the incense, in gospel times, should be spiritual, the worship plain, and the service of God enlarged, for in every place incense should be offered, Mal 1:11. 2. That it was to be placed before the veil, on the outside of that partition, but before the mercy-seat, which was within the veil, Exo 30:6. For though he that ministered at the altar could not see the mercy-seat, the veil interposing, yet he must look towards it, and direct his incense that way, to teach us that though we cannot with our bodily eyes see the throne of grace, that blessed mercy-seat (for it is such a throne of glory that God, in compassion to us, holds back the face of it, and spreads a cloud upon it), yet we must in prayer by faith set ourselves before it, direct our prayer, and look up. 3. That Aaron was to burn sweet incense upon this altar, every morning and every evening, about half a pound at a time, which was intended, not only to take away the ill smell of the flesh that was burnt daily on the brazen altar, but for the honour of God, and to show the acceptableness of his people's services to him, and the pleasure which they should take in ministering to him, Exo 30:7, Exo 30:8. As by the offerings on the brazen altar satisfaction was made for what had been done displeasing to God, so, by the offering on this, what they did well was, as it were, recommended to the divine acceptance; for our two great concerns with God are to be acquitted from guilt and accepted as righteous in his sight. 4. That nothing was to be offered upon it but incense, nor any incense but that which was appointed, Exo 30:9. God will have his own service done according to his own appointment, and not otherwise. 5. That this altar should be purified with the blood of the sin-offering put upon the horns of it, every year, upon the day of atonement, Exo 30:10. See Lev 16:18, Lev 16:19. The high priest was to take this in his way, as he came out from the holy of holies. This was to intimate to them that the sins of the priests who ministered at this altar, and of the people for whom they ministered, put a ceremonial impurity upon it, from which it must be cleansed by the blood of atonement.

II.This incense-altar typified, 1. The mediation of Christ. The brazen altar in the court was a type of Christ dying on earth; the golden altar in the sanctuary was a type of Christ interceding in heaven, in virtue of his satisfaction. This altar was before the mercy-seat; for Christ always appears in the presence of God for us; he is our advocate with the father (Jo1 2:1), and his intercession is unto God of a sweet-smelling savour. This altar had a crown fixed to it; for Christ intercedes as king. Father, I will, Joh 17:24. 2. The devotions of the saints, whose prayers are said to be set forth before God as incense, Psa 141:2. As the smoke of the incense ascended, so much our desires towards God rise in prayer, being kindled with the fire of holy love and other pious affections. When the priest was burning incense the people were praying (Luk 1:10), to signify that prayer is the true incense. This incense was offered daily, it was a perpetual incense (Exo 30:8); for we must pray always, that is, we must keep up stated times for prayer every day, morning and evening, at least, and never omit it, but thus pray without ceasing. The lamps were dressed or lighted at the same time that the incense was burnt, to teach us that the reading of the scriptures (which are our light and lamp) is a part of our daily work, and should ordinarily accompany our prayers and praises. When we speak to God we must hear what God says to us, and thus the communion is complete. The devotions of sanctified souls are well-pleasing to God, of a sweet-smelling savour; the prayers of saints are compared to sweet odours (Rev 5:8), but it is the incense which Christ adds to them that makes them acceptable (Rev 8:3), and his blood that atones for the guilt which cleaves to our best services. And, if the heart and life be not holy, even incense is an abomination (Isa 1:13), and he that offers it is as if he blessed an idol, Isa 66:3.

When he dresseth the lamps - Prepares the wicks, and puts in fresh oil for the evening.

Shall burn incense upon it - Where so many sacrifices were offered it was essentially necessary to have some pleasing perfume to counteract the disagreeable smells that must have arisen from the slaughter of so many animals, the sprinkling of so much blood, and the burning of so much flesh, etc. The perfume that was to be burnt on this altar is described Exo 30:34. No blood was ever sprinkled on this altar, except on the day of general expiation, which happened only once in the year, Exo 30:10. But the perfume was necessary in every part of the tabernacle and its environs.

And Aaron shall burn thereon sweet incense every morning,.... This in later times was done by a common priest, who obtained this service by lots as we find in the times of Zacharias, Luk 1:9 the incense was fetched out of the house of Abtines, where it was made, and burning coals were taken off of the altar of burnt offering in a vessel, and the incense was spread upon them and burnt: the Jewish canons about this matter run thus (r); he that was worthy of, or allotted to, the incense, took a vessel that held three kabs, and a bowl in the midst of it, full and heaped up with incense, and took a silver censer, and went up to the top of the altar, and moved the coals to and fro, and took them and went down and poured them into a golden censer: and again (s), he that was worthy of, or allotted to, a censer, gathered the coals upon the top of the altar, and spread them with the edges of the censer, and bowing himself went out; and he that was worthy of, or allotted to, the incense, took the bowl out of the midst of the vessel, and gave it to his friend or neighbour: and he that burns the incense may not burn until the president says to him, burn; and if he was an high priest, the president says, lord high priest, burn; the people depart, and he burns the incense, and bows and goes away: the burning of the sweet incense was typical of the mediation and intercession of Christ; the burning coals typified his sufferings, which were painful to his body, and in which he endured the wrath of God in his soul, and both must be very distressing to him: the incense put upon these shows that Christ's mediation and intercession proceeds upon his sufferings and death, his bloodshed, satisfaction, and sacrifice; which mediation of his, like the sweet incense, is frequent, is pure and holy, though made for transgressors, and there is none like unto it; there is but one Mediator between God and man: likewise this was typical of the prayers of the saints; and at the same time that the incense was burnt the people were at prayer, which was set before the Lord as incense, see Psa 141:3, these go upwards to God, and come up with acceptance to him, from off the golden altar, being offered up to him by Christ, with his much incense, through his blood and righteousness, and are pure, holy, fervent, and fragrant, and called odours, Rev 5:8.

when he dresseth the lamps, he shall burn incense upon it; which he did every morning he went into the holy place, where the candlestick with its lamps was; these he trimmed and dressed, snuffed those that were ready to go out, lighted those that were gone out, supplied them with oil and wicks, and cleared the snuff dishes, and the like: now near to the candlestick stood the altar of incense, so that when the priest looked after the one, he did the service of the other; and hence we learn, that our intercessor and lamplighter is one and the same; he that was seen amidst the golden candlesticks dressing the lamps of them, appears at the golden altar with a golden censer, to offer up the prayers of his saints, Rev 1:13 and we learn also, that the light of the word and prayer should go together, as they do in faithful ministers and conscientious Christians, who give themselves up unto and employ themselves therein; the one to and in the ministry of the word and prayer, and the other to and in the reading and hearing of the word and prayer.

Aaron shall burn thereon sweet incense--literally, "incense of spices"--Strong aromatic substances were burnt upon this altar to counteract by their odoriferous fragrance the offensive fumes of the sacrifices; or the incense was employed in an offering of tributary homage which the Orientals used to make as a mark of honor to kings; and as God was Theocratic Ruler of Israel, His palace was not to be wanting in a usage of such significancy. Both these ends were served by this altar--that of fumigating the apartments of the sacred edifice, while the pure lambent flame, according to Oriental notions, was an honorary tribute to the majesty of Israel's King. But there was a far higher meaning in it still; for as the tabernacle was not only a palace for Israel's King, but a place of worship for Israel's God, this altar was immediately connected with a religious purpose. In the style of the sacred writers, incense was a symbol or emblem of prayer (Psa 141:2; Rev 5:8; Rev 8:3). From the uniform combination of the two services, it is evident that the incense was an emblem of the prayers of sincere worshippers ascending to heaven in the cloud of perfume; and, accordingly, the priest who officiated at this altar typified the intercessory office of Christ (Luk 1:10; Heb 7:25).

every morning . . . at even--In every period of the national history this daily worship was scrupulously observed.
