The Book of Leviticus: God’s Holiness
Leviticus is named for its relation to the Levites, and most of its commands pertain to the priesthood, especially commands about atonement for sin, which is the subject of about half the book.
In Exodus, one of the most important phrases in the Old Testament is introduced: “I am the Lord.” In Leviticus, God says his nature is essentially holy (20:7-8, 21:8, etc.). In the ESV, the word “holy” is used 91 times in Book of Leviticus.
He is also the Lord who sanctifies or makes us holy (20:8; 21:8, 23; 22:9, 16; see also Ex. 31:13; Ezek. 20:12, 37:28, etc.). This is a key concept in Leviticus, repeated five times: “Be holy, for I am holy” (11:44-45, etc.). God’s holiness informs us about what it means for us to be holy, and God’s holiness is the reason that he provides atonement for us. This is the attribute of God most clearly on display in Leviticus, and nearly every passage in Leviticus can be seen through this lens.
Plain Teaching on Sin (ch. 1-7)
These commandments about sacrifice are filled with specific truth about sin and guilt. There is no need to seek any allegorical meaning in them, when they teach plain truths about sin and sacrifice:
1) We learn the difference between sins and trespasses (Ps. 19:12-13). There are sins that are obvious to us, but there are also sins that we commit unknowingly (4:2). 1 John 1:9 says that if we confess our (known) sin, he will cleanse us from all unrighteousness (which would include unknown sin).
2) We learn the difference between personal sin, public sin, and priestly sin (4:13, 22, 27). If I cheat my neighbor, that is my own sin. But Nehemiah acknowledged, for example, that the people had sinned corporately, and corporate repentance was required.
The sin of priests and leaders is also treated differently. Ministers and teachers of the Gospel carry more responsibility because of their consecration, and this even affects the way their families are treated.
3) We learn from Aaron’s four sons that there are sins of commission and omission. Just as Nadab and Abihu sinned by offering fire “which the Lord had not commanded” (10:1), Eleazar and Ithamar sinned by neglecting to eat the sacrifice as commanded priesthood(10:18).
Plain Teaching on Priesthood and Sacrifice (ch. 8-10, ch. 21-22)
The tabernacle is established in the Book of the Exodus, and the is established in this book. In Leviticus, we have plain teaching about the meaning of sacrifice—not only that God requires our best, or that he requires blood, but beyond that, we learn:
1) Sacrifice required confession (4:15, 5:5, 16:21). The purpose of placing hands on the animal was to confess guilt in its presence. Likewise, the sacrifice of Christ has no effect if we do not admit our guiltiness.
2) Sacrifice required consecration (ch. 8-10). Not everyone can make a sacrifice, but only a priest can make atonement under the Old Covenant (4:35, 5:16, etc.). But now the Lord requires consecration from all his children, and we are all priests in the new order (Heb. 7:11, 1 Pet. 2:5).
3) Sacrifice required cleanness. It is not undertaken flippantly (10:1), or in any place, or at any time (16:2). But under the New Covenant we learn that God seeks those who worship him “in spirit and in truth” (John 4:24). It is not just clean hands but “a pure heart” that the Lord desires (Ps. 24:4).
Holiness and Cleanliness (ch. 11-15)
All the rituals involving food, skin diseases, etc. may be seen as involving cleanliness, and may or may not involve the guilt of sin. The commandments about food (ch. 11) are practical and interesting. (Winkie Pratney says, if you break these commands, you won’t necessarily go to Hell, but you will feel like Hell.)
Before the New Covenant was established, the Lord frequently required healed lepers to abide by Leviticus 14 in presenting themselves to the priests.
Leviticus 13 and 14 are dedicated to the separation of those with contagious skin disorders from the crowd of the camp.
The idea that these diseases were transferred through physical contact, and not by some other mystical means, has suffered a lack of acceptance, even recently, even in the educated West. At the height of his career, Joseph Lister was criticized and laughed at in his early career for his ideas about cleanliness and antiseptics in hospitals; in his old age, Queen Victoria made him a baron and a royal counselor; now, he is known as the “Father of Modern Surgery.”
Day of Atonement (ch. 16)
The Day of Atonement, or Yom Kippur, is at the center of the Book of Leviticus, and it is central to the whole practice of making atonement. This is neither the same as the daily sacrifices, nor is it “business as usual.” We see this in 1) the rarity of the occasion, which was annual (v. 2, 29); 2) the entry of the Holy of Holies, which was not allowed at other times (v. 2); 3) the special release of the scapegoat, which is mentioned nowhere else in the Bible.
The meaning of the scapegoat is up for debate, but the custom is clear enough: In addition to the commands laid out in this passage—namely, confession over this goat—the high priest tied a scarlet thread to the goat, representing guilt, before sending him away. In later years, rather than merely releasing it, the man charged with the duty would push the goat off of a precipice, and wave a signal to people stationed nearby that the atonement ritual was complete. Regardless, it represents a distancing from sin (Ps. 103:12), God not counting our sins against us (Ps. 32:1-2, Rom. 4:7-8).
General Commands (ch. 17-20)
It is no coincidence that sex is mentioned so prominently (ch. 18) in a book about holiness and atonement; sexual immorality is the quickest path to deceive yourself and destroy your family, and must be taken seriously (Heb 13:4).
This section contains what Jesus called the second most important commandment: “Love your neighbor as yourself” (19:18). Thomas Fuller, a Puritan author, had a fascinating insight on this verse in connection with the Sermon on the Mount: “Many things pass to be in Scripture, when no such matter is to be found therein. ‘Ye have heard it said, “Thou shalt love thy neighbor, and hate thine enemy.”’ (Mt. 5:43) But where is it said, ‘Thou shalt hate thine enemy’? Surely nowhere in God’s Word.”
Feasts, Sabbaths and the Year of Jubilee (ch. 23-25, 27)
Note especially how the Feasts of Passover and Booths have been fulfilled in Christ’s death, and Pentecost, respectively (Mt. 26:2, 1 Cor. 5:7, etc.). (It’s important to know that Pentecost is simply the Greek name for the Feast of Booths.)
The Year of Jubilee (ch. 25) ensures justice and provide balances to the economic system; most interestingly, debt is freely forgiven, while in our modern system it simply accumulates unchecked.
Covenant and Consequences (ch. 26)
In Leviticus 26, God outlines consequences if Israel should fail to keep her side of the Covenant. This chapter shows that for believers, God will progressively try any means to get their attention, so that they will return to him (v. 3, 14, 18, 21, 23, 27; see also Deut. 28). But God promises in spite of this that he will bless and help them “if they confess their iniquity” (v. 40), and he could never forget or break his end of the covenant (v. 43-44).
This important section of the Pentateuch is what is referenced by Jeremiah and Daniel when they say that the punishments of the covenant have fallen on Israel (Dan. 9:10-14, Lam. 2:17). The complaints of other prophets of the exile period also prove that this Scripture was being fulfilled in their day (Hag. 2:16-17).
Written in Blood by Robert E. Coleman is a readable, well-studied devotional on the meaning of Jesus’ blood.
Andrew Murray published two books of sermons on Jesus’ blood: The Power of the Blood of Jesus and The Blood of the Cross.
