Jeremiah 23:38

But since ye say, the burden of the Lord,.... Seeing, notwithstanding all prohibitions of it, and directions to the contrary, they still persisted to call prophecy by this name, and that in a jocose and bantering way, and asked for it, and what it was, in a scoffing manner:

therefore thus saith the Lord, because you say this word, the burden of the Lord; will continue to use it, though so displeasing to me:

and I have sent unto you, saying, ye shall not say, the burden of the Lord; and therefore could not plead ignorance of his will, or excuse themselves, by saying they would have avoided it, had they known it was disagreeable to him: this was an aggravation of their impiety, that they should obstinately persist in it, after he had remonstrated against it by his messages to them.
