'Sixth' in the Bible

And I saw when he opened the sixth seal, and lo, a great earthquake came, and the sun became black as sackcloth of hair, and the moon became as blood,

And the sixth messenger did sound, and I heard a voice out of the four horns of the altar of gold that is before God,

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

And the sixth messenger did pour out his vial upon the great river, the Euphrates, and dried up was its water, that the way of the kings who are from the rising of the sun may be made ready;

the fifth, sardonyx; the sixth, sardius; the seventh, chrysolite; the eighth, beryl; the ninth, topaz; the tenth, chrysoprasus; the eleventh, jacinth; the twelfth, amethyst.
