Isaiah 17:12-14

Many warriors would descend on Israel like the waves of the sea, but they would quickly dissipate because the Lord would rebuke them. They would disappear like dust before a strong wind. The terror that would be so strong would vanish overnight. God also gave such a deliverance to Judah when Sennacherib the Assyrian attacked Jerusalem (cf. Isaiah 37:36), but that is not in view here. The fact that Isaiah did not mention a particular nation as the enemy, suggests that he had more in mind than just one foe, and a perspective that extended far beyond his own day. Many nations would punish Israel over the years.

What follows in chapter 18 is an example of how the nations are subject to God, the point of Isaiah 17:12-14. It describes an eschatological defeat of superpowers-one of which would destroy Damascus and Ephraim in Isaiah’s day.
