42:18-25 Observe the call given to this people, and the character given of them. Multitudes are ruined for want of observing that which they cannot but see; they perish, not through ignorance, but carelessness. The Lord is well-pleased in the making known his own righteousness. For their sins they were spoiled of all their possessions. This fully came to pass in the destruction of the Jewish nation. There is no resisting, nor escaping God's anger. See the mischief sin makes; it provokes God to anger. And those not humbled by lesser judgments, must expect greater. Alas! how many professed Christians are blind as the benighted heathen! While the Lord is well-pleased in saving sinners through the righteousness of Christ he will also glorify his justice, by punishing all proud despisers. Seeing God has poured out his wrath on his once-favoured people, because of their sins, let us fear, lest a promise being left us of entering into his rest, any of us should be found to come short of it.

24. Who—Their calamity was not the work of chance, but God's immediate act for their sins.

Jacob … Israel … we—change from the third to the first person; Isaiah first speaking to them as a prophet, distinct from them; then identifying himself with them, and acknowledging His share in the nation's sins (compare Jos 5:1).
