John Gill Commentary Leviticus 8:17

"But the bullock, and its skin, and its flesh, and its dung, he burnt with fire without the camp; as Jehovah commanded Moses." — Leviticus 8:17 (ASV)

But the bullock and his hide, his flesh, and his dung, he
burnt with fire without the camp
Aben Ezra observes, that some say that he did this himself; and others, that it was done by orders, that is, he ordered others to do it, which seems probable enough:

as the Lord commanded Moses ;
(Exodus 29:14) .
