That won't help you. Just like it happens in the New Testament, it was left up to the translator's preference.
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.KJV
gowy = apparently from the same root as 'gevah' (body) (in the sense of massing); a foreign nation; hence, a Gentile; also (figuratively) a troop of animals, or a flight of locusts:--Gentile, heathen, nation, people.
This same word is used for the nation of Israel, here:
Genesis 12:1-2 And the Lord said to Abram, Go forth out of thy land and out of thy kindred, and out of the house of thy father, and come into the land which I will shew thee. 2 And I will make thee a great nation, and I will bless thee and magnify thy name, and thou shalt be blessed.KJV

And one chapter before, there's this:
Isaiah 8:16 Bind up the Testimony, seal the Law among My Disciples. 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. 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.KJV
John 17:9 I pray for them: I pray not for the world, but for them which Thou hast given Me; for they are Thine.
Revelation 12:17 And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the Commandments of God, and have the Testimony of Jesus Christ.
This is the Gospel of the Kingdom.
Gee. . .and the translators of both the Hebrew and the Greek chose "Gentiles" for the translation.
Wonder why that was. . .surely couldn't be because it was correct, could it?
I dunno'. . .
Τοῦτο πρῶτον πίε· ταχὺ ποίει χώρα Ζαβυλὼν, ἡ γη Νεφθαλεὶν, καὶ οἱ
This first let you drink; quickly act O country of Zabulon, the land of Naphtali, and the

rest the the on sea coast, and beyond of the Jordan Galilee of the
Ethnos.
"Ethnology (from the Greek:
ἔθνος, ethnos meaning 'nation') is an academic field that compares and analyzes the characteristics of different peoples and the relationships between them (compare cultural, social, or sociocultural anthropology).--wikipedia.org/wiki/Ethnology
As the former time made light The land of Zebulun and the land of Naphtali, So the latter hath honoured the way of the sea, Beyond the Jordan, Galilee of the
nations.YLT
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.KJV
and he that is in anguish shall not be distressed only for a time. Drink this first. Act quickly, O land of Zabulon, land of Nephthalim, and the rest inhabiting the sea-coast, and the land beyond Jordan, Galilee of the
Gentiles.Brenton, LXX(Greek)
Gotta admit, the LXX is really weird in that verse... but that's what the NT chose. (shrug)
Gentiles doesn't always work, does it?
Matthew 21:43 Therefore say I unto you, The kingdom of God shall be taken from you, and given to
Gentiles bringing forth the fruits thereof.
John 18:35 Pilate answered, Am I a Jew? Thine own
Gentiles and the chief priests have delivered thee unto me: what hast thou done?
1 Peter 2:9 But ye [are] a chosen generation, a royal priesthood, an holy
Gentiles, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light:
Revelation 14:6 And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every
nation, and kindred, and tongue, and people,
