Isaiah 30:15

Into such small sherds, a heap thus scattered hither and thither, would the kingdom of Judah be broken up, in consequence of its ungodly thirst for self-liberation. "For thus saith the Lord Jehovah, the Holy One of Israel, Through turning and rest ye would be helped; your strength would show itself in quietness and confidence; but ye would not. And ye said, No, but we will fly upon horses; therefore ye shall flee: and, We will ride upon racehorses; therefore your pursuers will race. A thousand, ye will flee from the threatening of one, from the threatening of five, until ye are reduced to a remnant, like a pine upon the top of the mountain, and like a banner upon the hill." The conditions upon which their salvation depended, and by complying with which they would attain to it, were shūbhâh, turning from their self-chosen way, and nachath, rest from self-confident work of their own (from nūăch, like rachath, ventilabrum, from rūăch, and shachath, fovea, from shūăch). Their strength (i.e., what they would be able to do in opposition to the imperial power) would show itself (hâyâh, arise, come to the light, as in Isa 29:2), in hashqēt, laying aside their busy care and stormy eagerness, and bitchâh, trust, which cleaves to Jehovah and, renouncing all self-help, leaves Him to act alone. This was the leading and fundamental principle of the prophet's politics even in the time of Ahaz (Isa 7:4). But from the very first they would not act upon it; nor would they now that the alliance with Egypt had become an irreversible fact. To fly upon horses, and ride away upon racehorses (kal, like κέλης, celer) (Note: We regard the Sanscrit kal, to drive or hunt, the Greek κέλλ(ὀκέλλ)ειν, and the Semitic qal, as all having the same root: cf., Vurtius, Grundzge der griech.…

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).

30:15 The people of Judah needed to repent of their sinful ways (30:12-14), returning to the Lord, in order to be rescued. • Trust in the Lord would bring quietness and confidence, unlike their frantic negotiations with Egypt.
