'River' in the Bible

Now what have you to do in the way to Egypt, to drink the waters of the Shihor? Or what have you to do in the way to Assyria, to drink the waters of the River?

For he shall be as a tree planted by the waters, who spreads out its roots by the river, and shall not fear when heat comes, but its leaf shall be green; and shall not be careful in the year of drought, neither shall cease from yielding fruit.

Of Egypt: concerning the army of Pharaoh Necoh king of Egypt, which was by the river Euphrates in Carchemish, which Nebuchadnezzar king of Babylon struck in the fourth year of Jehoiakim the son of Josiah, king of Judah.

Don't let the swift flee away, nor the mighty man escape; in the north by the river Euphrates have they stumbled and fallen.

For that day is [a day] of the Lord, Yahweh of Armies, a day of vengeance, that he may avenge him of his adversaries: and the sword shall devour and be satiate, and shall drink its fill of their blood; for the Lord, Yahweh of Armies, has a sacrifice in the north country by the river Euphrates.
