In those days Yahweh began to send Rezin the king of Syria and Pekah the son of Remaliah against Judah. Bible

“Pekah the son of Remaliah.” Pekah was the king of Israel, so at that time Israel and Syria were both attacking Judah. By the time of Ahaz, Syria and Israel were allies and were working together to fight Judah (Isa. 7:1).
