Revelation 12:15

“And the serpent cast out of his mouth water as a flood, etc.] Which cannot design any persecution before the fall of Paganism, either of the Jews, or of the Romans; nor indeed the Arian persecution, since the casting out of this flood is distinguished from the above persecution, and was after the church began to flee upon that persecution; though it is not unusual for wicked persecutors, and violent persecutions, to be expressed by waters, and they are called proud waters, (<19C401>Psalm 124:1-4); and these may be said to be cast out of the mouth of the serpent, the devil, who was a persecutor and a murderer from the beginning, and by whom all persecutors and persecutions are instigated,…”

It is the mere product of the imagination, but the sense is clear. The woman is represented as having wings, and as being able thus to escape from the serpent. But, as an expression of his wrath, and as if with the hope of…”

“12:15-16 John pictures Satan as Leviathan (cp. Job 41:1) trying to destroy God’s people (the woman; see study note on Rev 12:1). The protective earth responds and the waters of chaos are contained, as at creation (cp. Gen 1:2, 6-7, 9-10).”
