Isaiah 9:2

The people that walked in darkness, namely, these same inhabitants of Galilee of the Gentiles, those who had been oppressed with spiritual darkness, have seen a great light, the prophet, speaking as the mouthpiece of the eternal and omniscient God, views the Messianic period as present even now, for so certain is the fulfillment of God's promise; they that dwell in the land of the shadow of death, in the darkness of heathendom, upon them hath the light shined, namely, that of salvation, of the wonderful spiritual blessings of the Savior. As the evangelist shows, Matthew 4:12, this prophecy was literally fulfilled during the Galilean ministry of Jesus, when He made Capernaum His headquarters and from there set forth on His journeys, not only throughout Galilee, but also into the country east of Jordan.
