Exodus 14:21
19 The angel of God, who was going before the camp of Israel, moved and went behind them, and the pillar of cloud moved from before them and stood behind them. 20 It came between the Egyptian camp and the Israelite camp; it was a dark cloud and it lit up the night so that one camp did not come near the other the whole night. 21 Moses stretched out his hand toward the sea, and the Lord drove the sea apart by a strong east wind all that night, and he made the sea into dry land, and the water was divided. 22 So the Israelites went through the middle of the sea on dry ground, the water forming a wall for them on their right and on their left. 23 The Egyptians chased them and followed them into the middle of the sea—all the horses of Pharaoh, his chariots, and his horsemen.
Revelation 16:12
10 Then the fifth angel poured out his bowl on the throne of the beast so that darkness covered his kingdom, and people began to bite their tongues because of their pain. 11 They blasphemed the God of heaven because of their sufferings and because of their sores, but nevertheless they still refused to repent of their deeds. 12 Then the sixth angel poured out his bowl on the great river Euphrates and dried up its water to prepare the way for the kings from the east. 13 Then I saw three unclean spirits that looked like frogs coming out of the mouth of the dragon, out of the mouth of the beast, and out of the mouth of the false prophet. 14 For they are the spirits of the demons performing signs who go out to the kings of the earth to bring them together for the battle that will take place on the great day of God, the All-Powerful.
Notes and References
"... As the largest river in southwest Asia, the Euphrates was never known to dry up, unlike most of the rivers in the Near East. The drying up of the river Euphrates to allow the kings of the east to cross over it is the typological antithesis of the Exodus from Egypt, in which the Israelites under Moses crossed the Reed Sea, and the later crossing of the Jordan under Joshua. The drying up of rivers is one of the responses of nature to the coming of God (Isaiah 50:2; Hosea 13:15; Nahum 1:4; see Jörg Jeremias, Theophanie, 90–97); it is also a miracle attributed to Ezekiel in "Vita Prophetarum" chapter 3, verse 7 (see Schwemer, “Vitae Prophetarum,” 242–48). The drying up of the Sea of Reeds (Exodus 14:21; compare Isaiah 11:15; Jeremiah 51:36) and the drying up of the Jordan River (Joshua 3:17) function as miraculous means enabling the passage of victorious armies ..."
