Isaiah 9:2 - Joseph Benson’s Commentary on the Old and New Testaments

The people Israel and Judah; that walked Or sat, as it is in Matthew 4:16; in darkness Both in the darkness of ignorance, and in the darkness of calamity; have seen a great light The prophet speaks of what was future, and would not take place till after seven hundred years, as though it were already arrived. Though “there would be very many among the Jews, to whom the Messiah, arising with his new light, would be an offence; who would resist his salutary doctrine, and who would therefore fall into the most grievous calamities, and thick darkness;” yet, “there would be others to whom the Messiah would truly appear with the light of grace and consolation, and who should receive him with the greatest joy, as attaining the summit of their hope and desire.” Accordingly, after the prophet had described the misery of those who, he foresaw, should reject him, he turns his style to describe the felicity of those on whom this Sun of righteousness should arise, setting forth both their joy and the cause of it.
