Revelation 12:15

And the serpent; the devil, the old serpent, mentioned Revelation 12:9, being able no longer to execute his malice as a dragon, by the civil power of the heathen emperors, tearing Christians in pieces, but discerning the church secured by the special providence of God, went to work another way. Cast out of his mouth water as a flood; corrupting the judgments of several persons, who, out of the abundance of error in their hearts, preached corrupt doctrine. Such were the followers of Arius, Nestorius, Eutyches, Pelagius, &c. The words of a man's mouth are as deep waters, Proverbs 18:4. The mouth of the wicked poureth out evil things, Proverbs 15:28. That he might cause her to be carried away of the flood; on purpose to ruin the church: and, indeed, such were the ill effects of these heresies, that he who is but meanly versed in the history of the fifth age, will see reason to adore the providence of God, that the Roman emperors, upon the sight of them, did not again turn pagans, and add their force to the malice of these pretended Christians against the sincerer part of the church.
