called by the Accadians id Idikla; i.e., "the river of Idikla", the third of the four rivers of Paradise (Gen. 2:14). Gesenius interprets the word as meaning "the rapid Tigris." The Tigris rises in the mountains of Armenia, 15 miles south of the source of the Euphrates, which, after pursuing a south-east course, it joins at Kurnah, about 50 miles above Bassorah. Its whole length is about 1,150 miles.
And the name of the third river is hiddekel: that is it which goeth toward the east of Assyria.
The third and fourth are the Euphrates and hiddekel which flow into the Persian gulf.
Phison and Euphrates, etc., three of the four rivers that watered Eden, the hiddekel being omitted.
hiddekel is the Tigris (in Armenia), the most rapid river of all.
The whole is surrounded by a wall, and in the park there is a lake whose waters are fed by the river hiddekel.
In the same form he also appeared to Daniel on the banks of the river hiddekel.
It is a very large and ancient city, situated on the river hiddekel (Tigris), and is connected with Nineveh by means of a bridge.
And the name of the third river is hiddekel; that is it which goeth toward the east of Assyria.
Hence the old Scriptural name hiddekel, signifying “swift or quick.”
