'Sixth' in the Bible

Then I saw Him open the sixth seal. A violent earthquake occurred; the sun turned black like sackcloth made of goat hair; the entire moon became like blood;

The sixth angel blew his trumpet. From the four horns of the gold altar that is before God, I heard a voice

say to the sixth angel who had the trumpet, “Release the four angels bound at the great river Euphrates.”

The sixth poured out his bowl on the great river Euphrates, and its water was dried up to prepare the way for the kings from the east.
