'As Sweet as Honey' in the Bible

And I went unto the angel, and said to 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 as sweet as honey."

And I took the little book out of his hand, and ate it up, and it was in my mouth as sweet as honey, and as soon as I had eaten it, my belly was bitter.
