The first thing which is here ordered to be made is the ark with its appurtenances, the furniture of the most holy place, and the special token of God's presence, for which the tabernacle was erected to be the receptacle.

I.The ark itself was a chest, or coffer, in which the two tables of the law, written with the finger of God, were to be honourably deposited, and carefully kept. The dimensions of it are exactly ordered; if the Jewish cubit was, as some learned men compute, three inches longer than our half-yard (twenty-one inches in all), this chest or cabinet was about fifty-two inches long, thirty-one broad, and thirty-one deep. It was overlaid within and without with thin plates of gold. It had a crown, or cornice, of gold, round it, with rings and staves to carry it with; and in it he must put the testimony, Exo 25:10-16. The tables of the law are called the testimony because God did in them testify his will: his giving them that law was in token of his favour to them; and their acceptance of it was in token of their subjection and obedience to him. This law was a testimony to them, to direct them in their duty, and would be a testimony against them if they transgressed. The ark is called the ark of the testimony (Exo 30:6), and the tabernacle the tabernacle of the testimony (Num 10:11) or witness, Act 7:44. The gospel of Christ is also called a testimony or witness, Mat 24:14. It is observable, 1. That the tables of the law were carefully preserved in the ark for the purpose, to teach us to make much of the word of God, and to hide it in our hearts, in our innermost thoughts, as the ark was placed in the holy of holies. It intimates likewise the care which divine Providence ever did, and ever will, take to preserve the records of divine revelation in the church, so that even in the latter days there shall be seen in his temple the ark of his testament. See Rev 11:19. 2. That this ark was the chief token of God's presence, which teaches us that the first and great evidence and assurance of God's favour is the putting of his law in the heart. God dwells where that rules, Heb 8:10. 3. That provision was made for the carrying of this ark about with them in all their removals, which intimates to us that, wherever we go, we should take our religion along with us, always bearing about with us the love of the Lord Jesus, and his law.

II.The mercy-seat was the covering of the ark or chest, made of solid gold, exactly to fit the dimensions of the ark, Exo 25:17, Exo 25:21. This propitiatory covering, as it might well be translated, was a type of Christ, the great propitiation, whose satisfaction fully answers the demands of the law, covers our transgressions, and comes between us and the curse we deserve. Thus he is the end of the law for righteousness.

III.The cherubim of gold were fixed to the mercy-seat, and of a piece with it, and spread their wings over it, Exo 25:18. It is supposed that these cherubim were designed to represent the holy angels, who always attended the shechinah, or divine Majesty, particularly at the giving of the law; not by any effigies of an angel, but some emblem of the angelical nature, probably some one of those four faces spoken of, Eze 1:10. Whatever the faces were, they looked one towards another, and both downward towards the ark, while their wings were stretched out so as to touch one another. The apostle calls them cherubim of glory shadowing the mercy-seat, Heb 9:5. It denotes their attendance upon the Redeemer, to whom they were ministering spirits, their readiness to do his will, their special presence in the assemblies of saints (Psa 68:17; Co1 11:10), and their desire to look into the mysteries of the gospel which they diligently contemplate, Pe1 1:12. God is said to dwell, or sit, between the cherubim, on the mercy-seat (Psa 80:1), and thence he here promises, for the future, to meet with Moses, and to commune with him, Exo 25:22. There he would give law, and there he would give audience, as a prince on his throne; and thus he manifests himself willing to be reconciled to us, and keep up communion with us, in and by the mediation of Christ. In allusion to this mercy-seat, we are said to come boldly to the throne of grace (Heb 4:16); for we are not under the law, which is covered, but under grace, which is displayed; its wings are stretched out, and we are invited to come under the shadow of them, Rut 2:12.

A mercy-seat - כפרת capporeth, from כפר caphar, to cover or overspread; because by an act of pardon sins are represented as being covered, so that they no longer appear in the eye of Divine justice to displease, irritate, and call for punishment; and the person of the offender is covered or protected from the stroke of the broken law. In the Greek version of the Septuagint the word ιλαστηριον, hilasterion, is used, which signifies a propitiatory, and is the name used by the apostle, Heb 9:5. This mercy-seat or propitiatory was made of pure gold; it was properly the lid or covering of that vessel so well known by the name of the ark and ark of the covenant. On and before this, the high priest was to sprinkle the blood of the expiatory sacrifices on the great day of atonement: and it was in this place that God promised to meet the people, (see Exo 25:22); for there he dwelt, and there was the symbol of the Divine presence. At each end of this propitiatory was a cherub, between whom this glory was manifested; hence in Scripture it is so often said that he dwelleth between the cherubim. As the word ιλαστηριον, propitiatory or mercy-seat, is applied to Christ, Rom 3:25, whom God hath set forth to be a Propitiation (ιλαστηριον) through faith in his blood - for the remission of sins that are past; hence we learn that Christ was the true mercy-seat, the thing signified by the capporeth, to the ancient believers. And we learn farther that it was by his blood that an atonement was to be made for the sins of the world. And as God showed himself between the cherubim over this propitiatory or mercy-seat, so it is said, God was in Christ reconciling the world unto himself; Co2 5:19, etc. See on Leviticus 7 (note).

And make one cherub on the one end, and the other cherub on the other end,.... The situation of the cherubim is particularly explained, lest, as Jarchi observes, it should be thought that there were two at both ends of the mercy seat; whereas there were only one at one end, and another at the other, opposite to each other, and both pointing to the mercy seat; which may express the situation and office of the ministers of the word under each dispensation, who are so placed as to derive all their gifts and graces from Christ, and to point him out unto the sons of men as the only way of salvation, the only propitiation for sin, and through whom alone grace and mercy are to be had:

even of the mercy seat shall ye make the cherubim on the two ends thereof; this is not so much intended the more to inculcate and confirm the situation of the cherubim, as more fully to explain the matter of which they were made; for it was "of" or out of the mercy seat that they were made, at the two ends of it; that is, they were made not only of the same kind of metal with that, but out of the same mass or lump of gold that was; a lid of gold being made commensurate to the ark, what remained above that measure, at the ends of it, were beaten and formed into two cherubim.

thou shalt make a mercy seat of pure gold--to serve as a lid, covering it exactly. It was "the propitiatory cover," as the term may be rendered, denoting that Christ, our great propitiation [Jo1 2:2; Jo1 4:10], has fully answered all the demands of the law, covers our transgressions, and comes between us and the curse of a violated law.
