Pekah came to the throne by assassinating
Pekahiah. He allied with Rezin of Damascus against Judah and attacked King
Ahaz, seeking to force Judah into their anti-Assyrian coalition. This crisis forms the setting for important prophecies in
Isaiah 7, including Isaiah's confrontation with Ahaz. Ahaz appealed to Tiglath-pileser III of Assyria, who captured extensive northern Israelite territory and deported inhabitants.
Hoshea son of
Elah then conspired against Pekah, killed him, and took the throne.
