In Numbers 15, the Lord instructs Moses to give the Israelites instructions regarding offerings and sacrifices. He begins by instructing them to offer a burnt offering, a grain offering, and a peace offering. He then goes on to explain the different types of offerings that can be made, including the sin offering, the guilt offering, and the wave offering. He also explains the importance of the tassels on the garments of the Israelites, which were to remind them of the Lord's commandments.
The Lord then goes on to explain the consequences for those who disobey His commands. He states that anyone who sins unintentionally must bring a female goat or lamb as a sin offering. He also states that anyone who sins defiantly must be cut off from the people.
The chapter ends with the Lord instructing Moses to tell the Israelites that when they enter the Promised Land, they must offer a special offering to the Lord. This offering is to be a reminder of the Lord's covenant with them.
Overall, this chapter is a reminder of the importance of following the Lord's commands and of the consequences for those who disobey. It also serves as a reminder of the Lord's covenant with the Israelites and of the special offering that they must make when they enter the Promised Land.
