'As Sweet as Honey' in the Bible

So I went to the angel and asked him to give me the little scroll. He said to me, "Take the scroll and eat it. It will make your stomach bitter, but it will be as sweet as honey in your mouth."

So I took the little scroll from the angel's hand and ate it, and it did taste as sweet as honey in my mouth, but when I had eaten it, my stomach became bitter.
