Revelation 12:2-4

New Revised Standard Version, Anglicised

² She was pregnant and was crying out in birth pangs, in the agony of giving birth. ³ Then another portent appeared in heaven: a great red dragon, with seven heads and ten horns, and seven diadems on his heads. ⁴ His tail swept down a third of the stars of heaven and threw them to the earth. Then the dragon stood before the woman who was about to bear a child, so that he might devour her child as soon as it was born.
