2 mishnayot! On sin-offerings - the procedure of how the slaughter, blood, altar, and eating the portions of the offering were all handled. This itemization includes the route the kohen would take on ascending the altar and walking around it (on the top) for the sake of putting the blood on the corners of the altar, with two views on how precisely those placements that needed to happen. Plus, a discussion of the red line that separates between the upper blood and the lower blood on the altar, and the source for it. Also - delineating kodshei kodshim and kodshei kalim, the gradations of holiness of the different sacrifices. Plus, how the division of the land according to tribes is manifest in the Temple - with part of it in Yehudah's portion and part of it in Binyamin's portion.
