'River' in the Bible

A river of fire was flowing,coming out from His presence.Thousands upon thousands served Him;ten thousand times ten thousand stood before Him.The court was convened,and the books were opened.

And I saw in a vision; and it came to pass, when I saw, that I was at Shushan in the palace, which is in the province of Elam; and I saw in a vision, and I was by the river of Ulai.

Then I lifted up mine eyes, and saw, and, behold, there stood before the river a ram which had two horns: and the two horns were high; but one was higher than the other, and the higher came up last.

And he came to the ram that had two horns, which I had seen standing before the river, and ran unto him in the fury of his power.

And I heard the voice of a man between the banks of the Ulai, which called out and said, “Gabriel, give this man (Daniel) an understanding of the vision.”

And in the four and twentieth day of the first month, as I was by the side of the great river, which is Hiddekel;

His sons will wage war, mustering a large army which will advance like an overflowing river and carrying the battle all the way to the enemy's fortress.

"At the time of the end the king of the south will attack him. Then the king of the north will storm against him with chariots, horsemen, and a large armada of ships. He will invade lands, passing through them like an overflowing river.

Then I Daniel looked, and, behold, there stood other two, the one on this side of the bank of the river, and the other on that side of the bank of the river.

And one said to the man clothed in linen, which was upon the waters of the river, How long shall it be to the end of these wonders?

And I heard the man clothed in linen, which was upon the waters of the river, when he held up his right hand and his left hand unto heaven, and sware by him that liveth for ever that it shall be for a time, times, and an half; and when he shall have accomplished to scatter the power of the holy people, all these things shall be finished.
