Chp. 4 verse 1 - chp. 5 verse 13: Begins with the laws of the sin offering. First the sin offering of a high priest who has erred and caused a mistaken action. It continues with an error in judgment taken by the high supreme court and the sin offering that they must bring. It then discusses the sacrifice brought by a ruler who has done a sin against one of the mitzvoth of the Torah. It goes on to discuss the laws of the sin offering of an individual. Chp. 5 continues with the laws of a guilt offering, if he can afford it a sheep, if not, then birds, and if not that, then a meal offering.
