Albert Barnes' Bible Commentary
Isaiah 30 - Introduction
It is probable that the prophecy in this chapter was delivered about the same time as that in the previous chapter, and on the same general occasion. It is evident that it refers to the time of Hezekiah, when the Jews were alarmed by an apprehended invasion of the king of Assyria. Hezekiah had revolted from the king of Assyria 2 Kings 18:7; and it is probable that many of the leaders of the Jews began to be alarmed at the prospect that their land would be invaded by him, especially as it was known that it was the intention of Sennacherib to make war on Egypt, and that he could easily take Judea in his way. In such circumstances it was natural that they should propose an alliance with the Egyptians, and seek to unite their forces with theirs to repel the common danger. Instead of looking to God, and relying on his aid, they had probably entered into such an alliance, offensive and defensive Isaiah 31:1. To see the impropriety of such a league, it is to be remembered that God had promised to be the protector of his people, and that he had prohibited alliances with the surrounding nations; that it was a leading part of the Jewish policy, as instituted by Moses, to keep them a distinct and independent people; and that special care had been exercised to keep them from returning to the customs, or depending on the aid of the Egyptians. This alliance had been formed unquestionably contrary to the solemn counsel and warning of Isaiah Isaiah 20:1, and he now reproves them for it, and endeavors to recall them again to confidence in God.
The following is a summary of the contents of the chapter:
I. The prophet denounces ‘wo’ on them for seeking the aid of Egypt Isaiah 30:1.
II. He assures them that Egypt would be unable to help them, and that the effect would be that they would yet be ashamed themselves of the alliance Isaiah 30:3.
III. The prophet is directed to make a solem record that the prevailing character of the Jews was that of a rebellious people Isaiah 30:8.
IV. The judgment of God is denounced against them for forming this alliance, under the image of a wall that is ready to fall on them, and destroy them Isaiah 30:12.
V. The prophet tells them of the true way in which they may have peace and confidence, and that is, by putting their trust in God, and assures them that God waits to become their defender Isaiah 30:15.
VI. God “would” yet bless them. The people would see the vanity of their reliance on Egypt, and would turn unto God, and their turning to him would be attended with most rich and valuable blessings. These blessings are described in highly figurative and beautiful language Isaiah 30:19)
VII. Yahweh would show himself the protector of his people; and would, in a signal and sudden manner, overthrow and destroy the Assyrian, and deliver his people Isaiah 30:27.
The scope, therefore, of the chapter is to lead them to look away from Egypt, and to put confidence in God, at whose hand they were about to experience so signal a deliverance from the much dreaded invasion of Sennacherib.
