Leviticus 10:16

The Law on the point in question was clear. See Leviticus 2:3, note; Leviticus 4:5, note; Leviticus 4:15 note. But on this occasion, though the sin-offering which had been offered by Aaron was for the people Leviticus 9:15, its blood was not carried into the tabernacle. The priests might therefore have too readily supposed that their eating the flesh, or burning it, was a matter of indifference. Hence, Moses explains that the appropriation of the flesh by the priests is an essential part of the act of atonement Leviticus 10:17.

It was burnt - It was consumed by fire in an ordinary way, not; in the fire of the altar. See Leviticus 1:9.
