And the voice which I heard from heaven spoke unto me again, and said, Go and take the little scroll which is open in the hand of the angel who stands upon the sea and upon the earth. And I went unto the angel, and said unto him, Give me the little scroll. And he said unto me, Take it, and eat it up; and it shall make your stomach bitter, but it shall be in your mouth sweet as honey.

And I took the little scroll out of the angel's hand, and ate it up; and it was in my mouth sweet as honey: and as soon as I had eaten it, my stomach was bitter. And he said unto me, you must prophesy again about many peoples, and nations, and tongues, and kings. (Revelation 10:8-11)
