Rezin

Meaning: firm; a prince

a king of Syria, who joined Pekah in an invasion of the kingdom of Judah (2 Kings 15:37; 16:5-9; Isaiah 7:1-8)

Ahaz induced Tiglath-pileser III to attack Damascus, and this caused Rezin to withdraw for the purpose of defending his own kingdom. Damascus was taken, and Rezin was slain in battle by the Assyrian king, and his people carried into captivity, 732 BC (2 Kings 16:9).
