Jeremiah 20:9 in the King James Version
Then I said, I will not make mention of him, nor speak any more in his name. But his word was in mine heart as a burning fire shut up in my bones, and I was weary with forbearing, and I could not stay.
Context
8 For as often as I speak, I cry out; I cry, “Violence and destruction!” because the LORD’s word has been made a reproach to me, and a derision, all day.
9 If I say that I will not make mention of him, or speak any more in his name, then there is in my heart as it were a burning fire shut up in my bones. I am weary with holding it in. I can’t.
10 For I have heard the defaming of many: “Terror on every side! Denounce, and we will denounce him!” say all my familiar friends, those who watch for my fall. “Perhaps he will be persuaded, and we will prevail against him, and we will take our revenge on him.”
