Revelation 18:24

And in her was found the blood of prophets, and of saints, and of all that were slain upon the earth.

Ver. 24. And in her was found] Rome hath ever been the slaughter house of the saints, as Jerusalem was before her, Matthew 23:34,39 .

And of all that were slain] For she hath a hand in all the wars of Europe, besides all the Christian blood shed by her instigation, in those holy wars, as they called them, for the recovery of the land of Canaan.
