When He (the Lamb) broke open the fifth seal, I saw underneath the altar the souls of those who had been slaughtered because of the word of God, and because of the testimony which they had maintained [out of loyalty to Christ].

Another angel came and stood at the altar. He had a golden censer, and much incense was given to him, so that he might add it to the prayers of all the saints (God’s people) on the golden altar in front of the throne.

And another angel came from the altar, the one who has power over fire; and he called with a loud voice to him who had the sharp sickle, saying, “Put in your sharp sickle and reap the clusters of grapes from the vine of the earth, because her grapes are ripe [for judgment].”

Then one of the seraphim flew to me with a burning coal in his hand, which he had taken from the altar with tongs.

And the Lord spoke to the man (seventh angel) clothed in linen and said, “Go between the whirling wheels under the cherubim; fill your hands with coals of fire from between the cherubim and scatter them over the city.” And he entered as I watched.

Even

And they sang the song of Moses, the bond-servant of God, and the song of the Lamb, saying,

“Great and wonderful and awe-inspiring are Your works [in judgment],

O Lord God, the Almighty [the Omnipotent, the Ruler of all];
Righteous and true are Your ways,
O King of the nations!

True

If anyone is destined for captivity, he will go into captivity; if anyone kills with a sword, he must be killed with a sword. Here is [the call for] the patient endurance and the faithfulness of the saints [which is seen in the response of God’s people to difficult times].

he too will [have to] drink of the wine of the wrath of God, mixed undiluted into the cup of His anger; and he will be tormented with fire and brimstone (flaming sulfur) in the presence of the holy angels and in the presence of the Lamb (Christ).

because His judgments are true and righteous. He has judged [convicted and pronounced sentence on] the great prostitute (idolatress) who was corrupting and ruining and poisoning the earth with her adultery (idolatry), and He has imposed the penalty for the blood of His bond-servants

on her.”
