Matthew Poole and continuators on Revelation 9:15

15 And the four angels were loosed which were prepared for an hour, and a day, and a month, and a year , for to slay the third part of men .

That is (say some) for any time whatsoever, God would have them move; or for that certain time which God had determined; but Mr. Mede hath here a peculiar notion; he observeth that an hour, and a day, and a month, and a year, make just 396 years. In a year are 365 days, in a month 30, which make 395, to which add the odd day, they make 396. The Turks begun their Empire under Ottoman, who began his Reign 1296: But their Leader Tangrolipix upon the taking of Bagdat was inaugurated, and put on the Imperial Robe, Anno 1057. Constantinople was taken by them 1453, between which are just 396 years▪

In which time they slew a numberless number of Men, called here the third part.
