“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.”
King James Version (KJV)
9:15 And the four angels were loosed, who were prepared - By loosing them, as well as by their strength and rage. To kill the third part of men - That is, an immense number of them. For the hour, and day, and month, and year - All this agrees with the slaughter which the Saracens made for a long time after Mahomet's death. And with the number of angels let loose agrees the number of their first and most eminent caliphs. These were Ali, Abubeker, Omar, and Osman. Mahomet named Ali, his cousin and son - in - law, for his successor; but he was soon worked out by the rest, till they severally died, and so made room for him. They succeeded each other, and each destroyed innumerable multitudes of men. There are in a prophetic Com. Years. Com. Days. Hour 8 Day 196 in all 212 years. Month 15 318 Year 196 117
Re 9:15 And the four angels were loosed. Whatever these angels represent, they are no longer restrained. It is implied that there were four agencies, or a fourfold division. Which were prepared for an hour, and a day, and a month, and a year. The Greek word "eniautos" used that for the regular solar year of 365-1/4 days, Julius Caesar having reformed the calendar. This would make 365-1/4, plus 30, plus 1, plus 1/12, equal 396-1/3 days. Or, a day being a symbol of a year, 396 years and four months.
