Revelation 10:8-11

8And the voice which I heard from heaven, I heard it again speaking with me, and saying, Go, take the book which is open in the hand of the angel that standeth upon the sea and upon the earth. 9And I went unto the angel, saying unto him that he should give me the little book. And he saith unto me, Take it, and eat it up; and it shall make thy belly bitter, but in thy mouth it shall be sweet as honey. 10And I took the little book out of the angel’s hand, and ate it up; and it was in my mouth sweet as honey: and when I had eaten it, my belly was made bitter. 11And they say unto me, Thou must prophesy again over many peoples and nations and tongues and kings.
