2. Special Instructions Concerning the Sacrifices for the Priests - Leviticus 6-7 The instructions contained in these two chapters were made known to "Aaron and his sons" (Lev 6:9, Lev 6:20, Lev 6:25), i.e., to the priests, and relate to the duties and rights which devolved upon, and pertained to, the priests in relation to the sacrifices. Although many of the instructions are necessarily repeated from the general regulations, as to the different kinds of sacrifice and the mode of presenting them; most of them are new, and of great importance in relation to the institution of sacrifice generally.
