'As Sweet as Honey' in the Bible

so I went to the angel, and said to him, "give me the little book." and he said to me, "take it, and eat it up; it shall prove bitter in thy bowels, but in thy mouth it shall be as sweet as honey."

immediately having took the little book out of the angel's hand, I swallowed it down: and in my mouth it was as sweet as honey: but as soon as I had swallowed it, it was bitter within me.
