'River' in the Bible

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

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.
