A mighty strong angel appeareth with a book open in his hand.
Revelation 10:1 And I saw another strong angel coming down out of heaven, arrayed with a cloud; and the rainbow was upon his head, and his face was as the sun, and his feet as pillars of fire; Revelation 10:2 and he had in his hand a little book open: and he set his right foot upon the sea, and his left upon the earth; Revelation 10:3 and he cried with a great voice, as a lion roareth: and when he cried, the seven thunders uttered their voices. Revelation 10:4 And when the seven thunders uttered [their voices], I was about to write: and I heard a voice from heaven saying, Seal up the things which the seven thunders uttered, and write them not. Revelation 10:5 And the angel that I saw standing upon the sea and upon the earth lifted up his right hand to heaven,
He sweareth by him that liveth for ever, that there shall be no more time.
Revelation 10:6 and sware by him that liveth for ever and ever, who created the heaven and the things that are therein, and the earth and the things that are therein, and the sea and the things that are therein, that there shall be delay no longer: Revelation 10:7 but in the days of the voice of the seventh angel, when he is about to sound, then is finished the mystery of God, according to the good tidings which he declared to his servants the prophets. Revelation 10:8 And the voice which I heard from heaven, [I heard it] again speaking with me, and saying, Go, take the book which is open in the hand of the angel that standeth upon the sea and upon the earth.
John is commanded to take and eat the book.
Revelation 10:9 And I went unto the angel, saying unto him that he should give me the little book. And he saith unto me, Take it, and eat it up; and it shall make thy belly bitter, but in thy mouth it shall be sweet as honey. Revelation 10:10 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 when I had eaten it, my belly was made bitter. Revelation 10:11 And they say unto me, Thou must prophesy again over many peoples and nations and tongues and kings.
