Apocalipsis 9

Y fueron desatados los cuatro ángeles que estaban aparejados para la hora y día y mes y año, para matar la tercera parte de los hombres.

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.

The four angels were freed who had been prepared for that hour and day and month and year, so that they might kill one third of mankind.
