Tubal

(1.) The fifth son of Japheth (Gen. 10:2).

(2.) A nation, probably descended from the son of Japheth. It
is mentioned by Isaiah (66:19), along with Javan, and by Ezekiel
(27:13), along with Meshech, among the traders with Tyre, also
among the confederates of Gog (Ezek. 38:2, 3; 39:1), and with
Meshech among the nations which were to be destroyed (32:26).
This nation was probably the Tiberini of the Greek historian
Herodotus, a people of the Asiatic highland west of the Upper
Euphrates, the southern range of the Caucasus, on the east of
the Black Sea.
