'River' in the Bible

Will the river-plant come up in its pride without wet earth? will the grass get tall without water?

The waters go from a pool, and a river becomes waste and dry;

He takes his rest under the trees of the river, and in the pool, under the shade of the water-plants.

Truly, if the river is overflowing, it gives him no cause for fear; he has no sense of danger, even if Jordan is rushing against his mouth.
