Revelation 10:9-10

9So I went to the angel and said to him, “Give me the little book.” And he said to me, “Take and eat it; and it will make your stomach bitter, but it will be as sweet as honey in your mouth.”

10Then I took the little book out of the angel’s hand and ate it, and it was as sweet as honey in my mouth. But when I had eaten it, my stomach became bitter.
