great red dragon
12:3 great red dragon. The sign of the great dragon is explained in Revelation 12:9. He is “that old serpent, called the Devil, and Satan,” who has tried to destroy the woman and her spiritual seed ever since Eden. Parenthetically, in order to be used as a sign, the dragon itself must have been a real animal, well known and feared by the ancient world but now extinct (see on Genesis 1:21; Job 40:15-24; Isaiah 27:1). Though evolutionists would disagree, dragons almost certainly were dinosaurs, universally known by the nations of antiquity to exist as real creatures.
