3 Bible Verses about Fire Of God's Word

Then I said, I will not make mention of him, nor speak any more in his name. But his word was in my heart as a burning fire shut up in my bones, and I was weary with forbearing, and I could not stay.

Is not my word like a fire? saith the LORD? and like a hammer that breaketh the rock in pieces?

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.
