Leviticus 10:18-20 New King James Version (NKJV)

18. See! Its blood was not brought inside the holy place; indeed you should have eaten it in a holy place, as I commanded.”

19. And Aaron said to Moses, “Look, this day they have offered their sin offering and their burnt offering before the Lord, and such things have befallen me! If I had eaten the sin offering today, would it have been accepted in the sight of the Lord?”

20. So when Moses heard that, he was content.
