CUT OUT THE PLAGUE SPOT

Cut out the plague spot. But that prophet or that dreamer of dreams shall be put to death, because he has counseled rebellion against the LORD your God who brought you from the land of Egypt and redeemed you from the house of slavery, to draw you away from the way in which the LORD your God has commanded you to walk. So you shall remove the evil from among you.

THE DEATH OF NADAB AND ABIHU

Now Nadab and Abihu, the sons of Aaron, took their respective [ceremonial] censers, put fire in them, placed incense on it and offered strange (unauthorized, unacceptable) fire before the LORD, [an act] which He had not commanded them to do.
And fire came out from the presence of the LORD and devoured them, and they died before the LORD.

LAWS ABOUT SOCIAL JUSTICE

You shall not harm or oppress any widow or fatherless child.
If you harm or oppress them in any way, and they cry at all to Me [for help], I will most certainly hear their cry;
and My wrath shall be kindled and burn; I will kill you with the sword, and your wives shall become widows and your children fatherless.
