Wherefore thus saith the Lord God of hosts, because ye speak this word,.... That it is not the Lord; it is not he that speaks; it is no prophecy of him, and therefore shall become wind, and come to nothing:
behold, I will make my word in thy mouth fire: it shall have its effect, and a dreadful one; it shall not become wind, but be as fire, not to enlighten the understanding, to purify the conscience, and warm the heart; but to torture, distress, and destroy, as the fire of the word out of the mouths of the two witnesses, Revelation 11:5:
and this people wood, and it shall devour them; as wood is devoured by fire, so shall this people be destroyed by sword and famine, as the word of the prophecy has declared they should; and which was done by the following means.
