Leviticus 10:18-22

Behold, since its blood had not been brought inside, into the sanctuary, you certainly should have eaten it in the sanctuary, just as I commanded!”

But Aaron said to Moses, “Behold, this very day they presented their sin offering and their burnt offering before the Lord. When things like these happened to me, if I had eaten a sin offering today, would it have been good in the sight of the Lord?”

When Moses heard that, it was good in his sight.
