This is some good writing. Or at least a great use of short declarative sentences to convey a powerful message.
The other two kids, Eleazar & Ithamar, messed up another offering in a way that is not clear to me. Perhaps they were supposed to no fully burn up the goat, but they did. This exchange goes like this,
and at least ends well.
When Moses inquired about the goat of the sin offering and found that it had been burned up, he was angry with Eleazar and Ithamar, Aaron’s remaining sons, and asked, 17 “Why didn’t you eat the sin offering in the sanctuary area? It is most holy; it was given to you to take away the guilt of the community by making atonement for them before the Lord. 18 Since its blood was not taken into the Holy Place, you should have eaten the goat in the sanctuary area, as I commanded.”
19 Aaron replied to Moses, “Today they sacrificed their sin offering and their burnt offering before the Lord, but such things as this have happened to me. Would the Lord have been pleased if I had eaten the sin offering today?” 20 When Moses heard this, he was satisfied.
It is kind of interesting to read about this. It's like, hey these rituals are frickin' complicated. And Aaron is not super fond of God or Moses getting all demanding with his boys. Very weird to encounter in the midst of several chapters of describing animal sacrifices over and over again.
Just for fun, here's something from the internet about what Aaron's outfit would look like. Seems real enough to me. The Umim and Thummim are tucked behind that jeweled breast plate.
