Revelation 9:14-16

Young's Literal Translation

¹⁴ saying to the sixth messenger who had the trumpet, `Loose the four messengers who are bound at the great river Euphrates;'

¹⁵ and loosed were the four messengers, who have been made ready for the hour, and day, and month, and year, that they may kill the third of men;

¹⁶ and the number of the forces of the horsemen [is] two myriads of myriads, and I heard the number of them.
