Observe here, 1. It is taken for granted that people would be inclined to bring offerings to the Lord. The very light of nature directs man, some way or other, to do honour to his Maker, and pay him homage as his Lord. Revealed religion supposes natural religion to be an ancient and early institution, since the fall had directed men to glorify God by sacrifice, which was an implicit acknowledgment of their having received all from God as creatures, and their having forfeited all to him as sinners. A conscience thoroughly convinced of dependence and guilt would be willing to come before God with thousands of rams, Mic. 6:6, 7. 2. Provision is made that men should not indulge their own fancies, nor become vain in their imaginations and inventions about their sacrifices, lest, while they pretended to honour God, they should really dishonour him, and do that which was unworthy of him. Every thing therefore is directed to be done with due decorum, by a certain rule, and so as that the sacrifices might be most significant both of the great sacrifice of atonement which Christ was to offer in the fulness of time and of the spiritual sacrifices of acknowledgment which believers should offer daily. 3. God gave those laws to Israel by Moses; nothing is more frequently repeated than this, The Lord spoke unto Moses, saying, Speak unto the children of Israel. God could have spoken it to the children of Israel himself, as he did the ten commandments; but he chose to deliver it to them by Moses, because they had desired he would no more speak to them himself, and he had designed that Moses should, above all the prophets, be a type of Christ, by whom God would in these last days speak to us, Heb. 1:2. By other prophets God sent messages to his people, but by Moses he gave them laws; and therefore he was fit to typify him to whom the Father has given all judgment. And, besides, the treasure of divine revelation was always to be put into earthen vessels, that our faith might be tried, and that the excellency of the power might be of God. 4. God spoke to him out of the tabernacle. As soon as ever the shechinah had taken possession of its new habitation, in token of the acceptance of what was done, God talked with Moses from the mercy-seat, while he attended without the veil, or rather at the door, hearing a voice only; and it is probable that he wrote what he heard at that time, to prevent any mistake, or a slip of memory, in the rehearsal of it. The tabernacle was set up to be a place of communion between God and Israel; there, where they performed their services to God, God revealed his will to them. Thus, by the word and by prayer, we now have fellowship with the Father, and with his Son Jesus Christ, Acts 6:4. When we speak to God we must desire to hear from him, and reckon it a great favour that he is pleased to speak to us. The Lord called to Moses, not to come near (under that dispensation, even Moses must keep his distance), but to attend and hearken to what should be said. A letter less than ordinary in the Hebrew word for called, the Jewish critics tell us, intimates that God spoke in a still small voice. The moral law was given with terror from a burning mountain in thunder and lightning; but the remedial law of sacrifice was given more gently from a mercy-seat, because that was typical of the grace of the gospel, which is the ministration of life and peace.
