'Sweet as Honey' in the Bible

And I went to the angel, saying to him, Give me the little book. And he saith to me, Take and eat it up, and it will make thy belly bitter, but it will be sweet as honey in thy mouth.

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, but when I had eaten it, my belly was bitter.
