Revelation 10:9-11King James Version (KJV)
9 And I went unto the angel, and said unto him, Give me the little book. And he said unto me, Take it, and eat it up; and it shall make thy belly bitter, but it shall be in thy mouth sweet as honey.
10 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 as soon as I had eaten it, my belly was bitter.
11 And he said unto me, Thou must prophesy again before many peoples, and nations, and tongues, and kings.
