These laws played an important role in foreshadowing the ultimate sacrifice of Christ.
When Christ paid for sin on the Cross, all sacrificial laws came to an end.
Hebrews 10:1-22 (NLT)
The old system in the law of Moses was only a shadow of the things to come, not the reality of the good things Christ has done for us. The sacrifices under the old system were repeated again and again, year after year, but they were never able to provide perfect cleansing for those who came to worship...8 Christ said, “You did not want animal sacrifices or grain offerings or animals burned on the altar or other offerings for sin, nor were you pleased with them” (though they are required by the law of Moses). 9 Then he added, “Look, I have come to do your will.” He cancels the first covenant in order to establish the second... 15 And the Holy Spirit also testifies that this is so. First he says, 16 “This is the new covenant I will make with my people on that day, says the Lord: I will put my laws in their hearts so they will understand them, and I will write them on their minds so they will obey them.” 17 Then he adds, “I will never again remember their sins and lawless deeds.” 18 Now when sins have been forgiven, there is no need to offer any more sacrifices. 19 And so, dear brothers and sisters, we can boldly enter heaven’s Most Holy Place because of the blood of Jesus. 20 This is the new, life-giving way that Christ has opened up for us through the sacred curtain, by means of his death for us. 21 And since we have a great High Priest who rules over God’s people, 22 let us go right into the presence of God, with true hearts fully trusting him. For our evil consciences have been sprinkled with Christ’s blood to make us clean, and our bodies have been washed with pure water.
