And the voice which I heard from heaven, I heard again speaking with me, and saying, “Go, take the book which is open in the hand of the angel who stands on the sea and on the land.” And I went to the angel, telling him to give me the little book. And he said to me, “Take it, and eat it; and it will make your stomach bitter, but in your mouth it will be sweet as honey.” And I took the little book out of the angel’s hand and ate it, and it was in my mouth sweet as honey; and when I had eaten it, my stomach was made bitter. And they said to me, “You must prophesy again concerning many peoples and nations and tongues and kings.”
Revelation 10:8-11
