Revelation 10:5-11

Then the angel whom I had seen standing on the sea and the land raised his right hand [to swear an oath] to heaven, [Deut 32:40; Dan 12:6, 7] and swore [an oath] by [the name of] 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, [Neh 9:6] but when it is time for the trumpet call of the seventh angel, when he is about to sound, then the mystery of God [that is, His hidden purpose and plan] is finished, as He announced the gospel to His servants the prophets. [Dan 12:6; Rom 11:25; 1 Cor 15:55; 2 Thess 2:7] Then the voice which I heard from heaven, I heard again speaking to me, and saying, “Go, take the book (scroll) which is open in the hand of the angel who is standing on the sea and on the land.” So I went up to the angel and told 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 as sweet as honey.” [Ezek 2:8, 9; 3:1-3] So I took the little book from the angel’s hand and ate it, and in my mouth it was as sweet as honey; but once I had swallowed it, my stomach was bitter. [Ps 119:103; Jer 15; 16] Then they said to me, “You must prophesy again concerning many peoples and nations and languages and kings.” [Jer 1:10]
