'Sixth' in the Bible

And I saw when the sixth stamp was undone, and there was a great earth-shock; and the sun became black as haircloth, and all the moon became as blood;

And at the sounding of the sixth angel a voice came to my ears from the horns of the gold altar which is before God,

Saying to the sixth angel who had the horn, Make free the four angels who are chained at the great river Euphrates.

And the sixth let what was in his vessel come out on the great river Euphrates; and it became dry, so that the way might be made ready for the kings from the east.

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