'River' in the Bible

And I saw in the vision; now it was so, that when I saw, I was in Shushan the palace, which is in the province of Elam; and I saw in the vision, and I was by the river 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 the two horns, which I saw standing before the river, and ran upon 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 the brink of the river on this side, and the other on the brink of the river on that side.

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

And I heard the man clothed in linen, who was above 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 a half; and when they have made an end of breaking in pieces the power of the holy people, all these things shall be finished.
