Revelation 9:13-15

The Voice

¹³ Then the sixth messenger sounded his trumpet; and I heard a voice from the four corners of the golden altar that is before God, ¹⁴ commanding the sixth messenger with the trumpet.

¹⁵ Then the four messengers, who had been held in chains until the hour and the day and the month and the year when they would kill one-third of humanity, were released.
