Revelation 9:14-16

Amplified Bible

¹⁴ saying to the sixth angel who had the trumpet, “Release the four angels who are bound at the great river Euphrates.” ¹⁵ So the four angels, who had been prepared for the [appointed] hour and day and month and year, were released to kill a third of mankind. ¹⁶ The number of the troops of cavalry was twice ten thousand times ten thousand (two hundred million); I heard the number of them.
