As we've said, prophetically, the rivers and the fountains of waters represent the sources of human life (cf. Isa 48:1 Ezek. 27:34 Rev. 8:11). Once again, the human race is in for horrific times. This time, those who want to destroy anyone with faith in God will be targeted.

5 And I heard the angel of the waters say, Thou art righteous, O Lord, which art, and wast, and shalt be, because thou hast judged thus.

Thou art righteous, O Lord, which art, and wast, and shalt be, because thou hast judged thus. The angel will not only "execute" his orders, but he will pronounce the justness of them — and he will do so by reminding all of creation of the life, sacrificial death, and resurrection of the Son of God.

6 For they have shed the blood of saints and prophets, and thou hast given them blood to drink; for they are worthy.

This language brings to mind Rom 12:19:
"Dearly beloved, avenge not yourselves, but rather give place unto wrath: for it is written, Vengeance is mine; I will repay, saith the Lord."

7 And I heard another out of the altar say, Even so, Lord God Almighty, true and righteous are thy judgments.

And I heard another out of the altar... This "another out of the altar" is a representative figure for the redeemed of mankind. They will concur with the Lord's angels that the almighty Creator is true and righteous in His judgments.

Remember, during the first 1/2 of Daniels 70th Week, the angels will be exerting care that the "seed of humanity" is preserved for the Kingdom Age. However, this 1/2 of Daniel's 70th Week will bring down the curtains on mankind and the planet earth. We're not told just how the angel will "use the sun" to scorch men — he could just cause the sun to heat up or he could change the orbit of the earth, only God knows — but we do know that this will just be the start of some hot times for the inhabitants of the earth which is destined to be destroyed by fire at the end of this final half of Daniel's 70th Week.

2Pe 3:7 But the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men.

2Pe 3:12 Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat?

9 And men were scorched with great heat, and blasphemed the name of God, which hath power over these plagues: and
they repented not to give him glory.

The attitude of those being scorched is not surprising when you consider that the Lord will have already harvested the earth, leaving only weeds and stubble.
