Jeremiah 28:7-9

7Nevertheless hear thou now this word that I speak in thine ears, and in the ears of all the people;

8The prophets that have been before me and before thee of old prophesied both against many countries, and against great kingdoms, of war, and of evil, and of pestilence.

9The prophet which prophesieth of peace, when the word of the prophet shall come to pass, then shall the prophet be known, that Yhwh hath truly sent him.
