When he opened the seventh seal, there was silence in heaven for about half an hour.
I saw the seven angels who stand before God, and seven shofars were given to them.
Another angel came and stood over the altar, having a golden censer. Much incense was given to him, that he should add it to the prayers of all the holy ones on the golden altar which was before the throne.
“HaShem said to Moses, Take to yourself sweet spices, gum resin, and onycha, and galbanum; sweet spices with pure frankincense: there shall be an equal weight of each; and you shall make incense of it, a perfume after the art of the perfumer, seasoned with salt, pure and holy: and you shall beat some of it very small, and put some of it before the testimony in the Tent of Meeting, where I will meet with you. It shall be to you most holy. The incense which you shall make, according to its composition you shall not make for yourselves: it shall be to you holy for HaShem. Whoever shall make any like that, to smell of it, he shall be cut off from his people.”
The smoke of the incense, with the prayers of the holy ones, went up before God out of the angel’s hand.
The angel took the censer, and he filled it with the fire of the altar, and threw it on the earth. There followed thunders, sounds, lightnings, and an earthquake.
The seven angels who had the seven shofars prepared themselves to sound.
The first sounded, and there followed hail and fire, mixed with blood, and they were thrown to the earth. One third of the earth was burnt up, and one third of the trees were burnt up, and all green grass was burnt up.
“Behold, tomorrow about this time I will cause it to rain a very grievous hail, such as has not been in Egypt since the day it was founded even until now…Moses stretched out his rod toward the heavens, and HaShem sent thunder, hail, and lightning flashed down to the earth. HaShem rained hail on the land of Egypt. So there was very severe hail, and lightning mixed with the hail, such as had not been in all the land of Egypt since it became a nation. The hail struck throughout all the land of Egypt all that was in the field, both man and animal, and the hail struck every herb of the field, and broke every tree of the field.”
Exodus 9:18, 23-25
The second angel sounded, and something like a great burning mountain was thrown into the sea. One third of the sea became blood,
“HaShem said to Moses, Tell Aaron, Take your rod, and stretch out your hand over the waters of Egypt, over their rivers, over their streams, and over their pools, and over all their ponds of water, that they may become blood; and there shall be blood throughout all the land of Egypt, both in vessels of wood and in vessels of stone.”
and one third of the living creatures which were in the sea died. One third of the ships were destroyed.
“The fish that were in the river died; and the river became foul, and the Egyptians couldn’t drink water from the river; and the blood was throughout all the land of Egypt.”
The third angel sounded, and a great star fell from the sky, burning like a torch, and it fell on one third of the rivers, and on the springs of the waters.
The name of the star is called Wormwood. One third of the waters became wormwood. Many people died from the waters, because they were made bitter.
The fourth angel sounded, and one third of the sun was struck, and one third of the moon, and one third of the stars; so that one third of them would be darkened, and the day wouldn’t shine for one third of it, and the night in the same way.
