Neither shalt thou go up by steps unto mine altar - The word altar comes from altus, high or elevated, though the Hebrew word מזבח mizbach, from זבח zabach, to slay, kill, etc., signifies merely a place for sacrifice; see Genesis 8:20. But the heathens, who imitated the rites of the true God in their idolatrous worship, made their altars very high; whence they derived their name altaria, altars, i.e., very high or elevated places; which they built thus, partly through pride and vain glory, and partly that their gods might the better hear them. Hence also the high places or idolatrous altars so often and so severely condemned in the Holy Scriptures. The heathens made some of their altars excessively high; and some imagine that the pyramids were altars of this kind, and that the inspired writer refers to those in these prohibitions. God therefore ordered his altars to be made,
In short, God formed every part of his worship so that every thing belonging to it might be as dissimilar as possible from that of the surrounding heathenish nations, and especially the Egyptians, from whose land they had just now departed. This seems to have been the whole design of those statutes on which many commentators have written so largely and learnedly, imagining difficulties where probably there are none. The altars of the tabernacle were of a different kind.
In this and the preceding chapter we have met with some of the most awful displays of the Divine Majesty; manifestations of justice and holiness which have no parallel, and can have none till that day arrive in which he shall appear in his glory, to judge the quick and the dead. The glory was truly terrible, and to the children of Israel insufferable; and yet how highly privileged to have God himself speaking to them from the midst of the fire, giving them statutes and judgments so righteous, so pure, so holy, and so truly excellent in their operation and their end, that they have been the admiration of all the wise and upright in all countries and ages of the world, where their voice has been heard! Mohammed defied all the poets and literati of Arabia to match the language of the Koran; and for purity, elegance, and dignity it bore away the palm, and remained unrivaled. This indeed was the only advantage which the work derived from its author; for its other excellences it was indebted to Moses and the prophets, to Christ and the apostles; as there is scarcely a pure, consistent, theological notion in it, that has not been borrowed from our sacred books. Moses calls the attention of the people, not to the language in which these Divine laws were given, though that is all that it should be, and every way worthy of its author; compressed yet perspicuous; simple yet dignified; in short, such as God should speak if he wished his creatures to comprehend; but he calls their attention to the purity, righteousness, and usefulness of the grand revelation which they had just received. For what nation, says he, is there so great, who hath God so nigh unto them, as Jehovah our God is, in all things that we call upon him for? And what nation hath statutes and judgments so righteous as all this law which I set before you this day? And that which was the sum of all excellence in the present case was this, that the God who gave these laws dwelt among his people; to him they had continual access, and from him received that power without which obedience so extensive and so holy would have been impossible; and yet not one of these laws exacted more than eternal reason, the nature and fitness of things, the prosperity of the community, and the peace and happiness of the individual, required. The Law is holy, and the Commandment is Holy, Just, and Good.
To show still more clearly the excellence and great utility of the ten commandments, and to correct some mistaken notions concerning them, it may be necessary to make a few additional observations. And
Nothing could be more appropriate as the commencement of the book of the covenant than these regulations for public worship. The rules for the building of altars must have been old and accepted, and are not inconsistent with the directions for the construction of the altar of the court of the tabernacle, Exodus 27:1-8 (compare Joshua 22:26-28).
