“Then the Lord said to Moses, ‘When you take a census of the Israelites to count them, each one must pay the Lord a ransom for his life at the time he is counted. Then no plague will come on them when you number them. Each one who crosses over to those already counted is to give a half shekel… This half shekel is an offering to the Lord. All who cross over, those twenty years old or more, are to give an offering to the Lord'” (Exodus 30:13-14, NIV).
The census was actually a way to determine a record of military manpower. But, when Moses enlisted men for military service, he was also to take a ransom from each twenty-year-old or more male and use it for the construction and ministry of the Tabernacle.
“Crossing over to those already counted” literally meant passing over to those who are mustered. It meant joining the ranks of the enlisted men. By passing muster the Israelite male effectively became a soldier in the Israeli militia–the Lord’s army.
“I will meet there with the sons of Israel, and it shall be consecrated by My glory. I will consecrate the tent of meeting and the altar; I will also consecrate Aaron and his sons to minister as priests to Me. I will dwell among the sons of Israel and will be their God. They shall know that I am the Lord their God who brought them out of the land of Egypt, that I might dwell among them; I am the Lord their God” (Exodus 29:43-46, NASB).
This chapter gives regulations for the consecration of the priests that would minister to God in the Tabernacle. The priests were to be ordained for service in the Tabernacle through purification rites and the offering of burnt sacrifices for atonement of sin. First, the priests were to be washed with water in the doorway of the Tabernacle. Then their priestly garments were placed on them and anointing oil poured over their heads.
“Then Moses took the blood from the basins and splattered it over the people, declaring, ‘ Look, this blood confirms the covenant the Lord has made with you in giving you these instructions.'” (Exodus 24:8, NLT).
After God had given the terms of the covenant to Moses, Israel agreed to its terms (vs. 3), which was then ratified in several ceremonial activities. These activities included the formal writing and reading of the covenant (vs. 4, 7), the splattering of blood (vs. 6), a covenant meal (vs. 11), and the appearing of the glory of the Lord on the mountain (vs. 15).
“He takes away the first to establish the second” (Hebrews 10:9, HCSB).
The Hebrews writer explains how the sacrifice of Christ on the cross replaced the Old Testament system of blood sacrifices and burnt offerings.
The Hebrews writer says that the Old Testament law was a representation of God’s reality, not the reality itself: “The law has only a shadow of the good things to come, and not the actual form of these realities” (vs. 1).
“But Aaron burned the incense and purified the people. He stood between the dead and the living, and the plague stopped.” (Numbers 16:47-48, NLT)
Numbers 16 is the record of yet another rebellion by the Israelites against Moses’ leadership and God’s authority.
This rebellion seemed to be a power struggle that was a more egregious challenge to God’s authority than any of the previous rebellions. This rebellion was led by certain Levites who had some of the most important duties related to the upkeep of the Tabernacle.
“And if any native Israelite or foreigner living among you eats or drinks blood in any form, I will turn against that person and cut him off from the community of your people, for the life of the body is in its blood. I have given you the blood on the altar to purify you, making you right with the Lord. It is the blood, given in exchange for a life, that makes purification possible.”
These verses explain the theology of substitutionary atonement.
Israel was forbidden to consume blood because blood was symbolic of the life given by God and was reserved as God’s portion of each animal sacrifice.
God had also designated the sacrificial blood as the means of atonement. In other words, God’s grace permitted the life of the animal to be a substitute in exchange for the life of the human sinner.
The sacrifice of Christ on the cross follows this same pattern for substitutionary atonement as described in Leviticus with the exception that Christ’s sacrifice, because He was God Incarnate, was once and for all while the sacrifice of bulls and goats had to be made repeatedly.
