Charles Spurgeon Commentary Jeremiah 5:12-14

"They have denied Jehovah, and said, It is not he; neither shall evil come upon us; neither shall we see sword nor famine: and the prophets shall become wind, and the word is not in them: thus shall it be done unto them. Wherefore thus saith Jehovah, the God of hosts, Because ye speak this word, behold, I will make my words in thy mouth fire, and this people wood, and it shall devour them." — Jeremiah 5:12-14 (ASV)

And said, It is not he; neither shall evil come upon us; neither shall we see sword nor famine: and the prophets shall become wind, and the word is not in them: thus shall it be done unto them. Wherefore thus saith the LORD God of hosts, Because ye speak this word, behold, I will make my words in thy mouth fire, and this people wood, and it shall devour them.

It is a dreadful state of things when God turns from pleading with men to threatening them, when he ceases to invite them to return to him, and denounces them as transgressors against his laws.

At such times, he makes the words that come out of the mouths of his prophets to be like fire, and men are utterly consumed by them as the stable in the field is destroyed by the devouring flames.
