This Ben-Hadad is called Hadad-idri or Hadad-ezer in the Assyrian texts; Ben-Hadad, in fact, was a god, who was worshipped by the Syrians by the side of his father Hadad.
In the struggle with Assyria the Aramaean forces were led by Hamath.

Most of the states of western Asia contributed troops; even the "Arabs" took part in the conflict.

But the confederates were overthrown with great slaughter at Karkar on the Orontes in B.C.853, and immediately afterwards we find Ahab at war with his late ally.

Hadad-idri lived only a few years longer.

In B.C.842 he was murdered by Hazael, who seized the throne.
