Revelation 9:13 - 10:11 NASB
5 Then the angel whom I saw standing on the sea and on the land lifted up his right hand to heaven, 6 and swore by Him who lives forever and ever, who created heaven and the things in it, and the earth and the things in it, and the sea and the things in it, that there will be delay no longer 7 but in the days of the voice of the seventh angel, when he is about to sound, then the mystery of God is finished, as He preached to His servants the prophets. 8 Then 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."
9 So I went to the angel, telling him to give me the little book. And he said to me, "Take it and eat it; it will make your stomach bitter, but in your mouth it will be sweet as honey." 10 I took the little book out of the angel's hand and ate it, and in my mouth it was sweet as honey; and when I had eaten it, my stomach was made bitter. 11 And they said to me, "You must prophesy again concerning many peoples and nations and tongues and kings."
