Apocalipse 8:5

And the angel... — Translate, And the angel has taken (or, took) the censer, and he filled it from the fire of the altar, and cast it (i.e., the fire or hot ashes which filled the censer) upon the earth. The prayers have gone up, and the sprinkling of the ashes earthward is the symbol of the answer descending from heaven. We may recall the similar action of Moses before Pharaoh, when he took ashes of the furnace and sprinkled it towards heaven, but it descended towards earth, as a symbol of the plague about to fall upon the land (Êxodo 9:8). The hot ashes are the tokens of the coming judgments. As in the parallel vision in Ezekiel (Ezequiel 10:2), when the man clothed with linen is bidden to “go in between the wheels, even under the cherub, and fill his hand with coals of fire from between the cherubims, and scatter them over the doomed city;” so here the ashes fall — the judgments are at hand

And there were voices ... — Or, And there took place thunders, and voices, and lightnings, and an earthquake. There is some variety among the MSS. in the order of the words here used. Some place “lightnings” before “voices.” These signs and sounds herald the approach of judgments. God has arisen in answer to the cry of His people. “The earth shook and trembled. There went up a smoke and a fire: coals were kindled at it. At the brightness that was before Him His thick clouds passed, hailstones and coals of fire. The Lord also thundered in the heavens, and the Highest gave His voice, hailstones and coals of fire. Yea, He sent out His arrows, and scattered them: He shot out lightnings and discomfited them... He delivered me from my strong enemy” (Salmos 18:4). It is a solemn thought that we may send up prayers, and the answer may come down a judgment; for often it is only through judgment that true loving-kindness can make her way.
