‏ Exodus 25:10-17

Verse 10

They shall make an ark - ארון aron signifies an ark, chest, coffer, or coffin. It is used particularly to designate that chest or coffer in which the testimony or two tables of the covenant was laid up, on the top of which was the propitiatory or mercy-seat, (see on Exo 25:17), and at the end of which were the cherubim of gold, (Exo 25:18-20), between whom the visible sign of the presence of the supreme God appeared as seated upon his throne. The ark was the most excellent of all the holy things which belonged to the Mosaic economy, and for its sake the tabernacle and the temple were built, Exo 26:33; Exo 40:18, Exo 40:21. It was considered as conferring a sanctity wherever it was fixed, 2 Chronicles 8;11; 2Sam 6:12.

Two cubits and a half shall be the length, etc. - About four feet five inches in length, taking the cubit as twenty-one inches, and two feet six inches in breadth and in depth. As this ark was chiefly intended to deposit the two tables of stone in, which had been written by the finger of God, we may very reasonably conjecture that the length of those tables was not less than four feet and their breadth not less than two. As to their thickness we can say nothing, as the depth of the ark was intended for other matters besides the two tables, such as Aaron's rod, the pot of manna, etc., etc., though probably these were laid up beside, not in, the ark.
Verse 11

A crown of gold round about - A border, or, as the Septuagint have it, κυματια χρυσα στεπτα κυκλω, waves of gold wreathed round about.
Verse 15

The staves - shall not be taken from it - Because it should ever be considered as in readiness to be removed, God not having told them at what hour he should command them to strike their tents. If the staves were never to be taken out, how can it be said, as in Num 4:6, that when the camp should set forward, they should put in the staves thereof, which intimates that when they encamped, they took out the staves, which appears to be contrary to what is here said? To reconcile these two places, it has been supposed, with great show of probability, that besides the staves which passed through the rings of the ark, and by which it was carried, there were two other staves or poles in the form of a bier or handbarrow, on which the ark was laid in order to be transported in their journeyings, when it and its own staves, still in their rings, had been wrapped up in the covering of what is called badgers' skins and blue cloth. The staves of the ark itself, which might be considered as its handles simply to lift it by, were never taken out of their rings; but the staves or poles which served as a bier were taken from under it when they encamped.
Verse 16

The testimony - The two tables of stone which were not yet given; these tables were called עדת eduth, from עד forward, onward, to bear witness to or of a person or thing. Not only the tables of stone, but all the contents of the ark, Aaron's rod, the pot of manna, the holy anointing oil, etc., bore testimony to the Messiah in his prophetic, sacerdotal, and regal offices.
Verse 17

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; 2Cor 5:19, etc. See on Leviticus 7 (note).
