For I have not sent them, saith the LORD, yet they prophesy a lie in my name; that I might drive you out, and that ye might perish, ye, and the prophets that prophesy unto you.
In my name. The devil often makes God's name the plea for lies (Matthew 4:6), and the plea for hypocrisy and hollow professions (Jeremiah 7:22-23). The lie of the false prophets is specified in Jeremiah 27:15-20. Their works, not their words, are the test whereby to know false prophets.
