'Eaten' in the Bible

So I went to the angel and asked him to give me the little book. "Take it," he said, "and eat the whole of it. You will find it bitter when you have eaten it, although in your mouth it will taste as sweet as honey."

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: and as soon as I had eaten it, my belly was bitter.
