Leviticus 10:1-3 ESV Now Nadab and Abihu, the sons of Aaron, each took his censer and put fire in it and laid incense on it and offered unauthorized fire before the Lord, which he had not commanded them. And fire came out from before the Lord and consumed them, and they died before the Lord. Then Moses said to Aaron, “This is what the Lord has said, ‘Among those who are near me I will be sanctified, and before all the people I will be glorified.’ ” And Aaron held his peace.

What a frightening and sobering day.   May we all fear the Lord because, although the Lord does not do such things every day (and like Ananias and Sapphira in Acts 5), he does eventually with all who don’t know him. His judgment will be just and severe.
