Observe here, 1. Concerning the trespass-offering, that, being much of the same nature with the sin-offering, it was to be governed by the same rules, Lev 7:6.

The fat that is on them - Chiefly the fat that was found in a detached state, not mixed with the muscles; such as the omentum or caul, the fat of the mesentery, the fat about the kidneys, etc. See Clarke's note on Lev 3:9, etc.
