Revelation 10:8-9

And I heard a voice from heaven, again speaking to me and saying: Go and take the book that is open, from the hand of the angel who standeth upon the sea and upon the earth.

And I went to the angel, saying unto him that he should give me the book. And he said to me: Take the book and eat it up. And it shall make thy belly bitter: but in thy mouth it shall be sweet as honey.
