NET

9 Sometimes I think, “I will make no mention of his message. I will not speak as his messenger anymore.” But then his message becomes like a fire locked up inside of me, burning in my heart and soul. I grow weary of trying to hold it in; I cannot contain it.

Darby

9 And 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.

KJV

9 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].
