That's an excellent point. Several references come to mind, such as:
Revelation 12:15 And the serpent cast out of his mouth water as a flood after the woman, that he might cause her to be carried away of the flood.
Revelation 12:16 And the earth helped the woman, and the earth opened her mouth, and swallowed up the flood which the dragon cast out of his mouth.
Revelation 12:17 And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.
