OT Prophecy NT Fulfillment
Isaiah 9:1-2b
"[1] Nevertheless the dimness shall not be such as was in her vexation, when at the first he lightly afflicted the land of Zebulun and the land of Naphtali, and afterward did more grievously afflict her by the way of the sea, beyond Jordan, in Galilee of the nations. [2] The people that walked in darkness have seen a great light: they that dwell in the land of the shadow of death, upon them hath the light shined."
Luke 2:28-32
"[28] Then took he him up in his arms, and blessed God, and said, [29] Lord, now lettest thou thy servant depart in peace, according to thy word: [30] For mine eyes have seen thy salvation, [31] Which thou hast prepared before the face of all people; [32] A light to lighten the Gentiles, and the glory of thy people Israel."

Tanakh - Neviim - Isaiah 8:23, 9:1b

"[8:23] For is there no gloom to her that was stedfast? Now the former hath lightly afflicted the land of Zebulun and the land of Naphtali, but the latter hath dealt a more grievous blow by the way of the sea, beyond the Jordan, in the district of the nations. [1] The people that walked in darkness have seen a great light; they that dwelt in the land of the shadow of death, upon them hath the light shined."
