In Leviticus 16:3, Aaron is told to bring a bull for sin offering, and a ram for burnt offering. He is later told in verse 5 to bring two male goats for sin offering and from what I see yet another ram for burnt offering. Throughout chapter 16, he is then given detailed instruction with regards to the bull and the two male goats. But he's not given detailed instructions about what to do with the ram(s). What's going on here?
