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.
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.
