Isaiah 9:2

The people that walked in darkness,.... Meaning not the inhabitants of Judah and Jerusalem, in the times of Hezekiah, when Sennacherib besieged them, as Jarchi and Kimchi interpret it; and much less the people of Israel in Egypt, as the Targum paraphrases it; but the inhabitants of Galilee in the times of Christ; see Mt 4:16 Joh 1:48 and is a true character of all the people of God before conversion, who are in a state of darkness, under the power of sin, shut up in unbelief; are in gross ignorance of themselves, and their condition; of sin, and the danger they are exposed to by it; of divine and spiritual things; of the grace of God; of the way of peace, life, and salvation by Christ; and of the work of the blessed Spirit; and of the truths of the Gospel; they are in the dark, and can see no objects in a spiritual sense; not to read the word, so as to understand it; or to work that which is good; and they "walk" on in darkness, not knowing where they are, and whither they are going; and yet of these it is said, theyhave seen a great light; Christ himself, who conversed among the Galilaeans, preached unto them, and caused the light of his glorious Gospel to shine into many of their hearts; by which their darkness was removed, so that they not only saw Christ, this great light, with their bodily eyes, but with the eyes of their understanding; who may be called the "light", because he is the author and giver of all light, even of nature, grace, and glory; and a "great" one, because he is the sun, the greatest light, the sun of righteousness, the light of the world, both of Jews and Gentiles; he is the true light, in distinction from all typical ones, and in opposition to all false ones, and who in his person is God over all.
