Revelation Chapter 10 Verse 6But in the days of the voice of the seventh angel, when he shall begin to sound, the mystery of God should be finished, as he hath declared to his servants the prophets.

By these three was the third part of men killed, by the fire, and by the smoke, and by the brimstone, which issued out of their mouths.

For their power is in their mouth, and in their tails: for their tails [were] like unto serpents, and had heads, and with them they do hurt.

And the rest of the men which were not killed by these plagues yet repented not of the works of their hands, that they should not worship devils, and idols of gold, and silver, and brass, and stone, and of wood: which neither can see, nor hear, nor walk:

Neither repented they of their murders, nor of their sorceries, nor of their fornication, nor of their thefts.

And I saw another mighty angel come down from heaven, clothed with a cloud: and a rainbow [was] upon his head, and his face [was] as it were the sun, and his feet as pillars of fire:

And he had in his hand a little book open: and he set his right foot upon the sea, and [his] left [foot] on the earth,

And cried with a loud voice, as [when] a lion roareth: and when he had cried, seven thunders uttered their voices.

And when the seven thunders had uttered their voices, I was about to write: and I heard a voice from heaven saying unto me, Seal up those things which the seven thunders uttered, and write them not.

And the angel which I saw stand upon the sea and upon the earth lifted up his hand to heaven,

And sware by him that liveth for ever and ever, who created heaven, and the things that therein are, and the earth, and the things that therein are, and the sea, and the things which are therein, that there should be time no longer:

And the voice which I heard from heaven spake unto me again, and said, Go [and] take the little book which is open in the hand of the angel which standeth upon the sea and upon the earth.

And I went unto the angel, and said unto him, Give me the little book. And he said unto me, Take [it], and eat it up; and it shall make thy belly bitter, but it shall be in thy mouth sweet as honey.

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 as soon as I had eaten it, my belly was bitter.

And he said unto me, Thou must prophesy again before many peoples, and nations, and tongues, and kings.

And there was given me a reed like unto a rod: and the angel stood, saying, Rise, and measure the temple of God, and the altar, and them that worship therein.

But the court which is without the temple leave out, and measure it not; for it is given unto the Gentiles: and the holy city shall they tread under foot forty [and] two months.

And I will give [power] unto my two witnesses, and they shall prophesy a thousand two hundred [and] threescore days, clothed in sackcloth.

These are the two olive trees, and the two candlesticks standing before the God of the earth.

And if any man will hurt them, fire proceedeth out of their mouth, and devoureth their enemies: and if any man will hurt them, he must in this manner be killed.

These have power to shut heaven, that it rain not in the days of their prophecy: and have power over waters to turn them to blood, and to smite the earth with all plagues, as often as they will.
