Ok, here’s the book you have been dreading reading! I will see if we can make it interesting. Here is an outline:

Chapters 1-5 cover the burnt offering, grain offering, peace offering, sin offering, and guilt offering. Great slide;

Several times after describing the particular offering it says, “Thus (with the animal sacrifice) the priest shall make atonement for him in regard to his sin which he has committed, and he will be forgiven.” But read Hebrews 10:1 For the Law, since it has only a shadow of the good things to come and not the very form of things, can never, by the same sacrifices which they offer continually year by year, make perfect those who draw near. 2 Otherwise, would they not have ceased to be offered, because the worshipers, having once been cleansed, would no longer have had consciousness of sins? 3 But in those sacrifices there is a reminder of sins year by year. 4 For it is impossible for the blood of bulls and goats to take away sins.” Sounds like a contradiction, doesn’t it? Perhaps this will help clear this up: Hebrews 9:13 For if the blood of goats and bulls and the ashes of a heifer sprinkling those who have been defiled sanctify for the cleansing of the flesh, 14 how much more will the blood of Christ, who through the eternal Spirit offered Himself without blemish to God, cleanse your conscience from dead works to serve the living God?” The blood of bulls and goats did “cleanse the flesh” but did not “cleanse the conscience”. Making an offering did forgive a sinner of his sin, but it wasn’t really the blood of animals that did it. Forgiveness was by the grace of God under the Law based on God knowing that He would one day use the blood of Jesus to forgive all sins. Once Jesus died, His blood “flowed backward and forward”. Backward to cover all those sins forgiven by the offerings under the Law. Hebrews 9:15 For this reason He is the mediator of a new covenant, so that, since a death has taken place for the redemption of the transgressions that were committed under the first covenant, those who have been called may receive the promise of the eternal inheritance.” David is an example of someone forgiven under the Law of Moses. David said ““Blessed are those whose lawless deeds have been forgiven, and whose sins have been covered.” (Romans 4:7) God forgave him of his sin with Bathsheeba, but it was by the blood of Jesus and the grace of God that he was forgiven. Maybe an example of all this is when you receive things bought with your credit card. You receive the purchased item immediately but the account is only settled at the end of the month when you pay the credit card bill. Sincere repentant sinners were forgiven under the old covenant but “on credit”, the final redemption price being paid with the blood of Jesus.
Hebrews goes on to discuss the old and the new covenants. Hebrews 9:16 For where a covenant is, there must of necessity be the death of the one who made it. 17 For a covenant is valid only when men are dead, for it is never in force while the one who made it lives. 18 Therefore even the first covenant was not inaugurated without blood. 19 For when every commandment had been spoken by Moses to all the people according to the Law, he took the blood of the calves and the goats, with water and scarlet wool and hyssop, and sprinkled both the book itself and all the people, 20 saying, “This is the blood of the covenant which God commanded you.” 21 And in the same way he sprinkled both the tabernacle and all the vessels of the ministry with the blood. (Exodus 23). 22 And according to the Law, one may almost say, all things are cleansed with blood, and without shedding of blood there is no forgiveness.” The author goes on to say that the Law was “about to disappear” at the time of writing (about 60 AD). Hebrews 8:13 When He said, “A new covenant,” He has made the first obsolete. But whatever is becoming obsolete and growing old is ready to disappear.” The old covenant did “disappear” in 70 AD when the Romans destroyed the temple and Jerusalem. Since 70 AD there have been no animal sacrifices, temple, or priesthood to offer sacrifices.
That’s about it for Leviticus 1-5. I hope this article has been helpful in your study.
