These chapters cover various laws. They begin with food laws of what the people should and should not eat. One of the purposes of these laws were to consecrate themselves in order to be holy, like God is holy (11:43-45). Then there were purification laws after having children, and people who had infectious skin diseases. Key words throughout this section is "clean and unclean." There was even a law that told the Israelites that once they were in the Promised Land, and they had built homes, if there was mildew in the home, they had guidelines on how to make it clean. There were other laws about human discharges, and how they were to become clean. The last chapter gave instructions to Aaron, that he was only to enter the Holy of Holies, one time a year, on the Day of Atonement. Here Aaron would offer a sin offering first for himself and his family, and then one for the people of Israel. There also was a "scape goat," and on his head was laid the sins of the people of Israel. He took their sins away until next year. This lesson also explained that in the NT, the writer explained that Jesus brought a new covenant when He bore the sins of many, and people who believe in Jesus, are atoned for and forgiven of their sin.
