'Sweet as Honey' in the Bible

So, I went to the angel and asked him to give me the little book. And he said to me, "Take it and eat it; it will be sweet as honey to your taste, but will cause you to have a sour stomach."

So, I took the little book from the angel's hand and ate it. And [sure enough], it was sweet as honey to my taste, but after eating it, it gave me a sour stomach.
