Ye shall not do so unto the Lord your God. The principal distinction, as far as regards the external exercises of devotion, is here laid down between the legitimate worship of God, and all the fictitious rites which the Gentiles have invented; viz., that God would have but one sanctuary and one altar, which might be a symbol of the difference between Himself and all idols; and thus that true religion should have no affinity to superstitions. To this refers the prohibition, that the Israelites should not conduct themselves towards God as the Gentiles did towards their idols; but that a barrier should be raised, which would separate them from the whole world. The whole external profession of God's worship is fitly annexed to the Second Commandment, because upon that it depends, and has no other object than its due observation. But when I begin to speak of the tabernacle, the priesthood, and the sacrifices, I am entering on a deep and vast ocean, in which many interpreters, whilst indulging their curiosity, have pursued a wild and wandering course. Admonished, therefore, by their example, I will take in my sails, and only touch upon a few points which tend to edification in the faith. But my readers must now be requested, not only to pardon me for abstaining from subtle speculations, but also themselves willingly to keep within the bounds of simplicity. Many have itching ears; and in our natural vanity, most men are more delighted by foolish allegories, than by solid erudition. But let those who shall desire to profit in God's school, learn to restrain this perverse desire of knowing more than is good for them, although it may tickle their minds. Now let us consider the words of Moses.

i. e., "The idolaters set up their altars and images on any high hill, and under every green tree at their pleasure, but ye shall not do so; the Lord Himself shall determine the spot for your worship, and there only shall ye seek Him." The religion of the Canaanites was human; its modes of worship were of man's devising. It fixed its holy places on the hills in the vain thought of being nearer heaven, or in deep groves where the silence and gloom might overawe the worshipper. But such superstitious appliances were not worthy of the true religion. God had revealed Himself to people in it, and manifested among them His immediate presence and power. He would Himself assign the sanctuary and the ritual of His own service.

Ye shall (c) not do so unto the LORD your God.
(c) You shall not serve the Lord with superstitions.

Ye shall not do so unto the Lord your God. Not sacrifice to him on hills and mountains, and under green trees; though the Jews commonly refer this to the destruction of the names of God, and of any thing appertaining to the temple; that though the temples and the altars of the Heathens were to be overthrown, yet not a stone was to be taken from the house of God, or that belonged to it, nor any of his names to be blotted out; so the Targum of Jonathan and Maimonides (z), who also observes (a), that whoever removes a stone by way of destruction from the altar, or from the temple, or from the court, is to be beaten; so he that burns the holy wood.
(z) Yesode Hattorah, c. 6. sect. 7, 9. (a) Ibid. sect. 8.

Not do so - That is, not worship him in several places, mountains, and groves.
