Leviticus 4:10BSB·traditional attribution

just as the fat is removed from the ox of the peace offering. Then the priest shall burn them on the altar of burnt offering.

Matthew Henry Presbyterian @wholebiblehenry

The laws contained in the first three chapters seem to have been delivered to Moses at one time. Here begin the statutes of another session, another day. From the throne of glory between the cherubim God delivered these orders. And he enters now upon a subject more strictly new than those before.

SIN OFFERING FOR THE PRIEST. (Lev. 4:3-35) If the priest that is anointed do sin--that is, the high priest, in whom, considering his character as typical mediator, and his exalted office, the people had the deepest interest; and whose transgression of any part of the divine law, therefore, whether done unconsciously or heedlessly, was a very serious offense, both as regarded himself individually, and the influence of his example.

Lev 4:8-10 The priest was to lift off “all the fat” from the sacrificial animal, i.e., the same fat portions as in the peace-offering (Lev 3:3-4, כּל־חלב is the subject to יוּרם in Lev 3:10), and burn it upon the altar of burnt-offering.
