The LORD will not spare him, but then the anger of the LORD and his jealousy shall smoke against that man, and all the curses that are written in this book shall lie upon him, and the LORD shall blot out his name from under heaven.
Ver. 20. The Lord will not spare him.] God cannot satisfy himself in threatening this heinous sin, as if the very naming of it had enraged his jealousy. Yea, when he threateneth it, he useth here no qualifications, as he doth in other cases, but is absolute in threatening, to show that he will be resolute in punishing. See the like in Isa 22:12-14 Ezekiel 24:13. It is better, therefore, to have a sore than a seared conscience; as a burning fever is more hopeful than a lethargy.
