Barnes' Notes on the Whole Bible

The crimes which are condemned in Leviticus 18:0; Leviticus 19:0 on purely spiritual ground, have here special punishments allotted to them as offences against the well-being of the nation.

Defile my sanctuary - i. e. pollute the people as identified with their sanctuary.

The burning under the sentence of the Law took place after the death of the criminal by stoning, or strangling. Joshua 7:25.

Cut off ... - See Exodus 31:14 note. The more full expression here used probably refers to some special form of public excommunication, accompanied, it may be, by expulsion from the camp.

They shall die childless - Either the offspring should not be regarded as lawfully theirs, nor be entitled to any hereditary privileges, or they should have no blessing in their children.

Any manner of living thing that creepeth - Rather, any creeping thing; that is, any vermin. See Leviticus 11:20-23. The reference in this verse is to dead animals, not to the creatures when alive.
