Jeremiah 20:8-9

8For as oft as I speak, I cry out; I proclaim violence and spoil; for the word of Jehovah is become unto me a reproach and a derision all the day.

9And I said, I will not make mention of him, nor speak any more in his name: but it was in my heart as a burning fire shut up in my bones; and I became wearied with holding in, and I could not.
