Jesaja 30:29

This is the issue of the judgment which begins at the house of God, then turns against the instrument employed, namely the heathen, and becomes to the Israel that survives a counterpart of the deliverance from Egypt. "Your song will then sound as in the night, when the feast is celebrated; and ye will have joy of heart like those who march with the playing of flutes, to go up to the mountain of Jehovah, to the Rock of Israel." In the word châg (feast), which is generally used with special reference to the feast of tabernacles, there is here an unmistakeable allusion to the passover, as we may see from the introduction of "the night," which evidently means the night before the passover (lēl shimmurı̄m, Exo 12:42), which was so far a festal night, that it preceded and introduced the feast of unleavened bread. The prophet has taken his figure from the first passover-night in Egypt, when Israel was rejoicing in the deliverance which it was just about to receive, whilst the destroying angel was passing through the land. Such would be the song which they would be able to sing, when Jehovah poured out His judgment upon His people's enemies outside. The church is shut up in its chamber (Isa 26:20), and its joy resembles the heartfelt joy of those who go on pilgrimage on one of the three great feasts, or in the procession that carries up the first-fruits to Jerusalem (Biccurim, iii. 3), going up with the sound of flutes to the mountain of Jehovah, to appear before Him, the Rock of Israel.

The prophecy of this chapter seems to relate (as that in the foregoing chapter) to the approaching danger of Jerusalem and desolations of Judah by Sennacherib's invasion. Here is, I. A just reproof to those who, in that distress, trusted to the Egyptians for help, and were all in a hurry to fetch succors from Egypt (Isa 30:1-7). II. A terrible threatening against those who slighted the good advice which God by his prophets gave them for the repose of their minds in that distress, assuring them that whatever became of others the judgment would certainly overtake them (Isa 30:8-17). III. A gracious promise to those who trusted in God, that they should not only see through the trouble, but should see happy days after it, times of joy and reformation, plenty of the means of grace, and therewith plenty of outward good things and increasing joys and triumphs (Isa 30:18-26), and many of these promises are very applicable to gospel grace. IV. A prophecy of the total rout and ruin of the Assyrian army, which should be an occasion of great joy and an introduction to those happy times (Isa 30:27-33).
