Leviticus 10:18

Behold, the blood of it. — According to the sacrificial law, the flesh of the sin offerings (the blood of which was not carried into the sanctuary) had to be eaten by the priests alone, in a holy place, as a part of the expiatory rites. (See Leviticus 6:25; Leviticus 10:17.) It was the flesh of those sin offerings, the blood of which was carried into the sanctuary, which had to be burnt. (See Leviticus 4:5; Leviticus 4:16; Leviticus 6:23; Leviticus 6:30.) Now the blood of the people’s sin-offering which was offered on this occasion was not carried into the sanctuary. (See Leviticus 9:9.)

Ye should indeed have eaten it. — Hence its flesh should have been eaten by Aaron and his two sons in the court-yard of the sanctuary, as Moses commanded in Leviticus 6:26.
