35 This is the portion of the anointing of Aaron, and of the anointing of his sons, out of the offerings of the Lord made by fire, in the day when he presented them to minister unto the Lord in the priest’s office;

36 Which the Lord commanded to be given them of the children of Israel, in the day that he anointed them, by a statute for ever throughout their generations.

37 This is the law of the burnt offering, of the meat offering, and of the sin offering, and of the trespass offering, and of the consecrations, and of the sacrifice of the peace offerings;

38 Which the Lord commanded Moses in mount Sinai, in the day that he commanded the children of Israel to offer their oblations unto the Lord, in the wilderness of Sinai.

Verse 38 informs us that these details were part of the instructions given to Moses in Mount Sinai. We heard about that event back in Exodus, including a brief explanation of these offerings, but apparently that was just an abbreviated form of what Moses was actually told. Here we are getting the fuller picture. The previous account was more concerned with the larger narrative of Moses and the Israelite exodus, so it merely mentioned that Moses received those laws, but it was not a 1-for-1 transcript of what he was told.

This makes sense from a narrative perspective, but now that we are delving into the particulars of the law we get the richer details. Interestingly, these particulars do end up shedding some new light on the narrative as well. As we have seen, God was instructing Moses on rituals that would teach the Israelites to put their sins and desires upon the altar, to consecrate their hearts and lives to the Lord, and to recognize God as the benefactor behind every overflowing blessing. And at this same time, at least some of the Israelites were showing the absence of these qualities as they gave themselves to a strange god instead, the golden calf. The Lord, Jehovah was not the object of their attention and desire, they were not sacrificing their sinful tendencies to better follow Him, and they were not in a spirit of gratitude for the rich blessings He had already given to them.

The message here is clear. The principles that God was delivering to Moses were not only generally correct for man to live by but were also exactly what the Israelites needed in that specific moment. The rituals were tailored to help them overcome their exact failings, to grow them in the way that they needed. It was going to take time, repetition, and sacrifice to make these lessons settle into the heart, and that’s exactly what God was setting up for them. It was, as Paul declared, the schoolmaster to make them ready for Christ.
