Jeremiah 23:16
Thus saith the LORD of hosts, Hearken not unto the words of the prophets that prophesy unto you: they make you vain: they speak a vision of their own heart, and not out of the mouth of the LORD.
Thus saith the Lord of hosts, hearken not unto the words of the prophets that prophesy unto you,.... Do not hear them; stop your ears at what they say; give no credit to them. The Targum is,
"do not receive the words of the false prophets that prophesy unto you:''
they make you vain; they filled their heads with vain and empty things, and their hearts with vain hopes, which deceived them; so the Targum,
"they deceive you;''
they taught them vain things, and made them vain and sinful in their lives and conversations; and therefore were not to be hearkened to:
they speak a vision of their own heart, and not out of the mouth of the LORD; what they imagined they saw was a device of their own hearts, and what was agreeable to them, which must be bad enough; a produce of their own brains; an invention of their own; mere doctrines of men, and not such as come from the mouth of God, are his revealed will, and according to his word; and therefore not to be hearkened to; for nothing is to be heard and received, in matters of religion, but what is according to the revelation of God's will in his word; see Isaiah 8:20. The Targum is,
"they speak to you the wickedness of their hearts, and not by the word of the Lord.''
