ha'-drak, had'-rak (chadhrakh): "The land of Hadrach" is mentioned only once in Scripture (Zec 9:1), and there it is grouped with Damascus, Hamath, Tyre and Sidon. It may be safely identified with the "Hatarikka" of the Assyrian inscriptions, against which Assur-dan III made expeditions in his 1st (772 BC), 8th and 18th years. It also appears in inscriptions of Tiglath-pileser III. They place it in the North of Lebanon.
