(14) The Lord God of hosts.--The solemn name (Jehovah Elohim Zebaoth) used for the second time in Jeremiah's teaching (Jeremiah 2:19). The message is partly to the people--"Because ye speak this word," partly to the prophet who was sent to bear his witness against them--"I will make my words in thy mouth."

Verse 14. - My words in thy mouth fire. (See on Jeremiah 1:9, 10.)

5:10-18 Multitudes are ruined by believing that God will not be so strict as his word says he will; by this artifice Satan undid mankind. Sinners are not willing to own any thing to be God's word, that tends to part them from, or to disquiet them in, their sins. Mocking and misusing the Lord's messengers, filled the measure of their iniquity. God can bring trouble upon us from places and causes very remote. He has mercy in store for his people, therefore will set bounds to this desolating judgment. Let us not overlook the nevertheless, ver. 18. This is the Lord's covenant with Israel. He thereby proclaims his holiness, and his utter displeasure against sin while sparing the sinner, Ps 89:30-35.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.
