Revelation 10:7-9

Young's Literal Translation

⁷ but in the days of the voice of the seventh messenger, when he may be about to sound, and the secret of God may be finished, as He did declare to His own servants, to the prophets.

⁸ And the voice that I heard out of the heaven is again speaking with me, and saying, `Go, take the little scroll that is open in the hand of the messenger who hath been standing upon the sea, and upon the land:'

⁹ and I went away unto the messenger, saying to him, `Give me the little scroll;' and he saith to me, `Take, and eat it up, and it shall make thy belly bitter, but in thy mouth it shall be sweet -- as honey.'
