Revelation 14:20 - Matthew Poole's English Annotations on the Holy Bible

And the winepress was trodden without the city: by the city, Dr. More thinks Babylon is here meant, and that the meaning is, that the powerful convictions of the word before mentioned, shall not reach Babylon, the Romish hierarchy and polity, as being hardened against any such thing. But Mr. Mede and others think, that the city of Jerusalem is here meant, or the Holy Land, which comprehends exactly one thousand six hundred furlong, that is, two hundred Italian miles, or one hundred and sixty Grecian miles. But what that place shall be, where this slaughter shall be, is a great secret. And blood came out of the winepress, even unto the horse bridles, by the space of a thousand and six hundred furlongs: it is plain it shall be a great slaughter, by the depth of the blood mentioned, and the length of the ground which it should to that depth overflow. It is very probable, that great battle is meant, mentioned Revelation 19:20,21, in the place called Armageddon, upon the pouring out of the sixth vial, Revelation 16:16. In so difficult a business nothing can be positively determined.
