Revelation 16:21

Now Yahweh said to Moses, “Stretch out your hand toward the sky, that there may be hail on all the land of Egypt, on man and on beast and on every plant of the field, throughout the land of Egypt.”

“Have you entered the storehouses of the snow, Or have you seen the storehouses of the hail,

Therefore, thus says Lord Yahweh, “I will make a stormy wind break out in My wrath. There will also be in My anger a flooding rain and hailstones to consume it in wrath.

And the sanctuary of God which is in heaven was opened, and the ark of His covenant appeared in His sanctuary, and there were flashes of lightning and sounds and peals of thunder and an earthquake and a great hailstorm.

Then I heard a loud voice from the sanctuary, saying to the seven angels, “Go and pour out on the earth the seven bowls of the wrath of God.”

And men were scorched with fierce heat, and they blasphemed the name of God who has the authority over these plagues, and they did not repent so as to give Him glory.

and they blasphemed the God of heaven because of their pains and their sores, and they did not repent of their deeds.

I bear witness to everyone who hears the words of the prophecy of this book: If anyone adds to them, God will add to him the plagues which are written in this book.
