Leviticus 10:3

Then Moses said to Aaron, “This is what the LORD meant when He said: ‘To those who come near Me I will show My holiness, and in the sight of all the people I will reveal My glory.’” But Aaron remained silent.

Then Moses said unto Aaron, This is it that the LORD spake, saying, I will be sanctified in them that come nigh me, and before all the people I will be glorified. And Aaron held his peace.
