What the Bible says about Burning People to Death

Some crimes are so heinous that the guilty must be burned to death.
(Like when a man has sex with his wife and mother-in-law, the daughter of a priest behaves like a whore, or someone touches the accursed thing.)

If a man take a wife and her mother, it is wickedness: they shall be burnt with fire, both he and they; that there be no wickedness among you. -- Leviticus 20:14

And the daughter of any priest, if she profane herself by playing the whore, she profaneth her father: she shall be burnt with fire. -- Leviticus 21:9

Sometimes God burns people to death.
(Like when they complain too much, burn incense without a license, dabble in astrology, or make God angry or jealous or something. And sometimes God burns people to identify a prophet or to identify himself, and sometimes for no reason at all.)

And Nadab and Abihu, the sons of Aaron, took either of them his censer, and put fire therein, and put incense thereon, and offered strange fire before the LORD, which he commanded them not. And there went out fire from the LORD, and devoured them, and they died before the LORD. -- Leviticus 10:1-2
