Then Moses said to Aaron and to his [younger] sons Eleazar and Ithamar, “Do not uncover your heads nor let your hair hang loose nor tear your clothes [as expressions of mourning], so that you will not die [also] and so that He will not express His wrath and anger toward all the congregation. But your relatives, the whole house of Israel, may mourn the burning which the Lord has brought about.

Then the Lord spoke to Moses after the death of the two sons of Aaron who had died when they [irreverently] approached the presence of the Lord.

You shall not give any of your children to offer them [by fire as a sacrifice] to Molech [the god of the Ammonites], nor shall you profane the name of your God [by honoring idols as gods]. I am the Lord.

You shall not go around as a gossip among your people, and you are not to act against the life of your neighbor [with slander or false testimony]; I am the Lord.
