Leviticus 1:12ESV·traditional attribution

And he shall cut it into pieces, with its head and its fat, and the priest shall arrange them on the wood that is on the fire on the altar,

Matthew Henry Presbyterian @wholebiblehenry

Here we have the laws concerning the burnt-offerings, which were of the flock or of the fowls. Those of the middle rank, that could not well afford to offer a bullock, would bring a sheep or a goat; and those that were not able to do that should be accepted of God if they brought a turtle-dove or a pigeon.

And he shall cut it into his pieces, with his head and his fat,.... Or "his body", as the Targum of Jonathan; this was to be cut in pieces in the same manner as the bullock; see Gill on Lev 1:6, and the priest shall lay them in order on the wood that is on the fire, which is on the altar; See Gill on Lev 1:8.
