Exodus 9:9
8 Then the Lord said to Moses and Aaron, “Take handfuls of soot from a furnace, and have Moses throw it into the air while Pharaoh is watching. 9 It will become fine dust over the whole land of Egypt and will cause boils to break out and fester on both people and animals in all the land of Egypt.” 10 So they took soot from a furnace and stood before Pharaoh, Moses threw it into the air, and it caused festering boils to break out on both people and animals. 11 The magicians could not stand before Moses because of the boils, for boils were on the magicians and on all the Egyptians.
Revelation 16:2
1 Then I heard a loud voice from the temple declaring to the seven angels: “Go and pour out on the earth the seven bowls containing God’s wrath.” 2 So the first angel went and poured out his bowl on the earth. Then ugly and painful sores appeared on the people who had the mark of the beast and who worshiped his image. 3 Next, the second angel poured out his bowl on the sea, and it turned into blood, like that of a corpse, and every living creature that was in the sea died. 4 Then the third angel poured out his bowl on the rivers and the springs of water, and they turned into blood. 5 Now I heard the angel of the waters saying:“You are just—the one who is and who was, the Holy One—because you have passed these judgments, 6 because they poured out the blood of your saints and prophets, so you have given them blood to drink. They got what they deserved!”
Notes and References
"... The seven bowl plagues are enumerated in Revelation 16:2–21: (1) The plague of sores or boils (verse 2; the sixth plague of Exodus 9:9) affects those who had received the brand of the beast and worshiped its image (continuing these motifs first mentioned in 13:15–16 and reiterated in 14:9–11). (2) The sea becomes blood, killing all sea creatures (verse 3), parallel to the effects of the second trumpet plague in 8:8–9 and reminiscent of the first plague of Exodus 7:20–21. (3) The rivers and wells become blood (verse 4), also reminiscent of the first plague of Exodus 7:20–21. This bowl plague is accompanied by a “judgment doxology” sung by a mysterious angel of the water, emphasizing the justice of God in avenging the death of his prophets and saints (verses 5–7). (4) The sun scorches people (verses 8–9; partially resembles the fire from heaven of the seventh plague of Exodus 9:22–24). (5) The throne of the beast (already mentioned in 13:2) and its kingdom are covered with darkness (verse 10), reminiscent of the ninth plague of Exodus 10:21 ..."
