Tigris River in Smiths Bible Dictionary
is used by the LXX. as the Greek equivalent of the Hebrew
Hiddekel, and occurs also in several of the apocryphal books,
as in Tobit, ch. 6:1, Judith, ch. 1:6, and Ecclesiasticus, ch.
24:25. The Tigris, like the Euphrates, rises from two
principal sources in the Armenian mountains, and flows into
the Euphrates. Its length, exclusive of windings, is reckoned
at 1146 miles. It receives, along its middle and lower course
no fewer than five important tributaries. These are the river
of Zakko or eastern Khabour, the Great Zab (Zab Ala), the
Lesser Zab (Zab Asfal), the Adhem, and the Diyaleh or ancient
Gyndes. All these rivers flow from the high range of Zagros.
We find but little mention of the Tigris in Scripture. It
appears, indeed, under the name of Hiddekel, among the rivers
of Eden, Ge 2:14 and is there correctly described as "running
eastward to Assyria;" but after this we hear no more of it, if
we accept one doubtful allusion in Nahum Na 2:6 until the
captivity, when it becomes well known to the prophet Daniel.
With him it is "the Great River." The Tigris, in its upper
course, anciently ran through Armenia and Assyria.
