Leviticus 10:12

And Moses spake unto Aaron. — This communication, which refers to the sacrifices offered on the eighth day, or the day after the consecration was finished, Moses made to Aaron and his two surviving sons immediately after the calamity that had befallen them. As Aaron lost his two eldest sons in consequence of their having violated the sacrificial regulations, Moses is most anxious to guard him and his two younger sons against transgressing any other part of the ritual connected with the same sacrifices, lest they also should incur a similar punishment.

Take the meat offering that remaineth of the offerings. — The meat offering which was offered by the nation the day after the consecration, when the calamity happened (see Leviticus 9:17), and which was not as yet eaten. With the exception of the handful which was burnt on the altar, all belonged to the priests. (See Leviticus 2:1; Leviticus 6:14.)

And eat it without leaven beside the altar. — That is, in the court of the tent of meeting, where the altar of burnt offering stood. (See Leviticus 6:16.)

For it is most holy. — Hence it could only be eaten by the male members of the families of the priests within the court of the sanctuary. (See Leviticus 6:18.)
