Jeremiah 26:4

And thou shalt say unto them,.... What follows is the substance of the prophecy, and the sum of the sermon or discourse he was sent to deliver, without diminishing a word of it:

thus saith the Lord, if ye will not hearken to me, to walk in my law which I have set before you; first by Moses, by whose hands it was given to their fathers; and by the prophets, the interpreters of it to them; before whom it was set as a way for them to walk in, and a rule to walk by; a directory for them in their lives and conversations; and which continues to be so, as it is set before us Christians by our King and Lawgiver Jesus Christ; though not to obtain righteousness and life by the works of it; which should not be sought for, nor are attainable thereby.
