Isaiah 7:7-9

In contrast to what the two enemy kings said (Isaiah 7:6), the sovereign God assured Ahaz that the evil that Judah’s enemies had planned for her would not materialize. By pointing out that the head of Syria was Damascus and the head of Damascus was Rezin, God was contrasting the limited sovereignty of Rezin with His own. This is also the point of His reference to the "son of Remaliah" being over Samaria, which was Ephraim’s capital. An additional point may be that these nations would remain as they were without the addition of Judah. They would not conquer Judah. [Note: See Young, 1:274.] God promised that Israel would not be a people (i.e., would be destroyed as a nation) within 65 years. The Northern Kingdom suffered defeat in 722 B.C., only about 13 years from then. To make matters worse, in 671 B.C., about 62 years after this prophecy, King Esarhaddon began importing foreign settlers into the former Northern Kingdom, which made return and resettlement there impossible (cf. 2 Kings 17:24; 2 Chronicles 33:11; Ezra 4:2; Ezra 4:10).

Ahaz’s responsibility, and the responsibility of all who heard this prophecy (the "you" is plural), especially the government leaders, was to believe this promise of God and trust Him. If they would not believe it, they would not last.

"Only through trusting in the present and ultimate veracity of God is any real security possible." [Note: Oswalt, p. 202.]

"God literally says, ’If you do not firm up, you will not be confirmed.’ In other words, ’You’ll live by faith, or you won’t live at all. But if you do want my support, all you have to do is lean on me.’ God is attracted to weakness and need and honesty. He is repelled by our self-assured pride." [Note: Ortlund, p. 89.]
