New King James Version (NKJV)
Revelation 9
17 And thus I saw the horses in the vision: those who sat on them had breastplates of fiery red, hyacinth blue, and sulfur yellow; and the heads of the horses were like the heads of lions; and out of their mouths came fire, smoke, and brimstone.
18 By these three plagues a third of mankind was killed--by the fire and the smoke and the brimstone which came out of their mouths.
19 For their power is in their mouth and in their tails; for their tails are like serpents, having heads; and with them they do harm.
20 But the rest of mankind, who were not killed by these plagues, did not repent of the works of their hands, that they should not worship demons, and idols of gold, silver, brass, stone, and wood, which can neither see nor hear nor walk.
21 And they did not repent of their murders or their sorceries or their sexual immorality or their thefts.
Revelation 10
1 I saw still another mighty angel coming down from heaven, clothed with a cloud. And a rainbow was on his head, his face was like the sun, and his feet like pillars of fire.
2 He had a little book open in his hand. And he set his right foot on the sea and his left foot on the land,
3 and cried with a loud voice, as when a lion roars. When he cried out, seven thunders uttered their voices.
4 Now when the seven thunders uttered their voices, "Seal up the things which the seven thunders uttered, and do not write them."
5 The angel whom I saw standing on the sea and on the land raised up his hand to heaven
6 and swore by Him who lives forever and ever, who created heaven and the things that are in it, the earth and the things that are in it, and the sea and the things that are in it, that there should be delay no longer,
