Leviticus 9:14

‘And he washed the innards and the legs, and burnt them on the whole burnt offering on the altar.’

Then Aaron washed the innards and the legs and burnt them also on the altar. Thus was purification and atonement made for him. In the same way Jesus too was offered ‘piece by piece’ as through His earthly life He suffered many things, and would suffer worse at the end. But thereby His offering when it was made was sufficient for the whole world.
