Commentaries
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.
19. my servant—namely, Israel. Who of the heathen is so blind? Considering Israel's high privileges, the heathen's blindness was as nothing compared with that of Israelite idolaters.
my messenger … sent—Israel was designed by God to be the herald of His truth to other nations.
perfect—furnished with institutions, civil and religious, suited to their perfect well-being. Compare the title, "Jeshurun," the perfect one, applied to Israel (compare Isa 44:2), as the type of Messiah [Vitringa]. Or translate, the friend of God, which Israel was by virtue of descent from Abraham, who was so called (Isa 41:8), [Gesenius]. The language, "my servant" (compare Isa 42:1), "messenger" (Mal 3:1), "perfect" (Ro 10:4; Heb 2:10; 1Pe 2:22), can, in the full antitypical sense, only apply to Christ. So Isa 42:21 plainly refers to Him. "Blind" and "deaf" in His case refer to His endurance of suffering and reproach, as though He neither saw nor heard (Ps 38:13, 14). Thus there is a transition by contrast from the moral blindness of Israel (Isa 42:18) to the patient blindness and deafness of Messiah [Horsley].
