'River' in the Bible

saying to the sixth angel, the one holding the trumpet, "Set free the four angels who are bound at the great river Euphrates!"

Then the serpent spouted water like a river out of his mouth after the woman in an attempt to sweep her away by a flood,

but the earth came to her rescue; the ground opened up and swallowed the river that the dragon had spewed from his mouth.

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

Then the angel showed me the river of the water of life -- water as clear as crystal -- pouring out from the throne of God and of the Lamb,

flowing down the middle of the city's main street. On each side of the river is the tree of life producing twelve kinds of fruit, yielding its fruit every month of the year. Its leaves are for the healing of the nations.
