Revelation 10:7-9

Darby Translation

⁷ but in the days of the voice of the seventh angel, when he is about to sound the trumpet, the mystery of God also shall be completed, as he has made known the glad tidings to his own bondmen the prophets.

⁸ And the voice which I heard out of the heaven [was] again speaking with me, and saying, Go, take the little book which is opened in the hand of the angel who is standing on the sea and on the earth.

⁹ And I went to the angel, saying to him to give me the little book. And he says to me, Take and eat it up: and it shall make thy belly bitter, but in thy mouth it shall be sweet as honey.
