'River' in the Bible

It said to the sixth angel--the angel who had the trumpet, "Set at liberty the four angels who are prisoners near the great river Euphrates."

And the serpent poured water from his mouth--a very river it seemed--after the woman, in the hope that she would be carried away by its flood.

But the earth came to the woman's help: it opened its mouth and drank up the river which the Dragon had poured from his mouth.

The sixth angel poured his bowl into that great river, the Euphrates; and its stream was dried up in order to clear the way for the kings who are to come from the east.

Then he showed me the river of the Water of Life, bright as crystal, issuing from the throne of God and of the Lamb.

On either side of the river, midway between it and the main street of the city, was the Tree of Life. It produced twelve kinds of fruit, yielding a fresh crop month by month, and the leaves of the tree served as medicine for the nations.
