Isaiah 1:1 The vision of Isaiah the son of Amoz, which he saw concerning Judah and Jerusalem in the days of Uzziah, Jotham, Ahaz, and Hezekiah, kings of Judah.
Isaiah 8:18 Behold, I and the children whom the LORD hath given me are for signs and for wonders in Israel from the LORD of hosts, which dwelleth in mount Zion. 8:19 And when they shall say unto you, Seek unto them that have familiar spirits, and unto wizards that peep, and that mutter: should not a people seek unto their God? for the living to the dead? 8:20 To the law and to the testimony: if they speak not according to this word, it is because there is no light in them. 8:21 And they shall pass through it, hardly bestead and hungry: and it shall come to pass, that when they shall be hungry, they shall fret themselves, and curse their king and their God, and look upward. 8:22 And they shall look unto the earth; and behold trouble and darkness, dimness of anguish; and they shall be driven to darkness.
Isaiah 9:1 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. 9:2 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. 9:3 Thou hast multiplied the nation, and not increased the joy: they joy before thee according to the joy in harvest, and as men rejoice when they divide the spoil.
Isaiah 9:6 For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace. 9:7 Of the increase of his government and peace there shall be no end, upon the throne of David, and upon his kingdom, to order it, and to establish it with judgment and with justice from henceforth even for ever. The zeal of the LORD of hosts will perform this. 9:8 The Lord sent a word into Jacob, and it hath lighted upon Israel.
Isaiah 29:18 And in that day shall the deaf hear the words of the book, and the eyes of the blind shall see out of obscurity, and out of darkness. 29:19 The meek also shall increase their joy in the LORD, and the poor among men shall rejoice in the Holy One of Israel. 29:20 For the terrible one is brought to nought, and the scorner is consumed, and all that watch for iniquity are cut off: 29:21 That make a man an offender for a word, and lay a snare for him that reproveth in the gate, and turn aside the just for a thing of nought. 29:22 Therefore thus saith the LORD, who redeemed Abraham, concerning the house of Jacob, Jacob shall not now be ashamed, neither shall his face now wax pale. 29:23 But when he seeth his children, the work of mine hands, in the midst of him, they shall sanctify my name, and sanctify the Holy One of Jacob, and shall fear the God of Israel. 29:24 They also that erred in spirit shall come to understanding, and they that murmured shall learn doctrine.
Matthew 4:12 Now when Jesus had heard that John was cast into prison, he departed into Galilee; 4:13 And leaving Nazareth, he came and dwelt in Capernaum, which is upon the sea coast, in the borders of Zabulon and Nephthalim: 4:14 That it might be fulfilled which was spoken by Esaias the prophet, saying, 4:15 The land of Zabulon, and the land of Nephthalim, by the way of the sea, beyond Jordan, Galilee of the Gentiles; 4:16 The people which sat in darkness saw great light; and to them which sat in the region and shadow of death light is sprung up.
Though all that asserts that within borders within the area known as Galilee of the Gentiles was the land of the two Israelite Tribes: Zebulon and Nephtalim - you are asserting that was Gentiles He came to liberate from the above Deuteronomical vexation; am I reading you right as to that?
If so, then you are off, way off.
