Revelation 10:9-11

And 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. And 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. And they say unto me, Thou must prophesy again over many peoples and nations and tongues and kings.
