Revelation 10:9-10

And I went to the Angel, saying to him that he should give the book to me. And he said to me: "Receive the book and consume it. And it shall cause bitterness in your stomach, but in your mouth it shall be sweet like honey." And I received the book from the hand of the Angel, and I consumed it. And it was sweet like honey in my mouth. And when I had consumed it, my stomach was made bitter.
