Leviticus 10:18

(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 6:25-26; 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.
