Jeremiah 26:5

To hearken to the words of my servants the prophets
The interpretations they give of the law; the doctrines they deliver; the exhortations, cautions, and reproofs given by them in the name of the Lord, whose servants they were; and therefore should be hearkened to; since hearkening to them is hearkening to the Lord himself, in whose name they speak, and whose message they deliver: whom I sent unto you, both rising up early and sending [them];
they had their mission and commission from the Lord; and who was careful to send them early, if they might be instruments to do them good and prevent their ruin; they had the best of means, and these seasonable, and so were left without excuse: (but ye have not hearkened);
neither to the Lord, nor to his prophets; but went on in their own ways, neglecting the law of the Lord and the instructions of his servants.
