2 Kings 16:5
Then Rezin king of Syria and Pekah son of Remaliah king of Israel came up to Jerusalem to war: and they besieged Ahaz, but could not overcome him. Then Rezin king of Syria and Pekah son of Remaliah king of Israel came up to Jerusalem to war: and they besieged Ahaz, but could not overcome him.
Rezin king of Syria and Pekah son of Remaliah king of Israel came up together to war against Jerusalem and besieged Ahaz there, yet they could not overcome him. The very existence of Judah was imperiled by this invasion, coming in a time of rapid decline of the kingdom. The crisis was the direct result of the idolatrous course of Ahaz, pursued in spite of earnest prophetic appeals. Because of that course the wrath of the Lord rested upon Judah and Jerusalem, delivering them to trouble and to astonishment and to hissing.
The alliance of Syria and Israel against Judah was unnatural, and true servants of the Most High would have had no fear of it. But repeated transgression had shorn Ahaz and his chief men of strength. The king and his people were left stricken with nameless dread of the retributive judgments of an offended God. Their hearts were moved as the trees of the wood are moved with the wind.
In that crisis God sent Isaiah to meet the trembling king with the charge to take heed and be quiet, to fear not nor be fainthearted. The divine message was that the evil counsel of Syria and Ephraim and the son of Remaliah to vex Judah and to set up a new king over it would not stand nor come to pass. Both Syria and Israel would soon come to an end. Judah itself would be established only through belief, for without belief it would not be established.
This history belongs to the history of the Jews later held up before them to show their own future as the result of their course of action. It illustrates how for thousands of years they forged fetters that bound them in a bondage which no human power could break.
