The other Ten Tribes of Israel, who are NOT jewish, are collectively known as "The House of Israel".
Zaragoza in the Ebro (Hebrew) Valley was originally called ZARAH-GASSA which means "Stronghold of ZARAH." ZARAH / ZERAH was one of Judah's twin sons (Genesis 38:28-30), Judah himself being ONE (the fourth) of Jacob/Israel's TWELVE sons and a Hebrew.
Closer to Gibraltar, the River Guadalquivir was called, by the Moorish invaders, "Wadi-al-Hibri" meaning "River of the Hebrews." (So Gadites were still there.)
Cadiz was originally called "Gaderia" or "Gad's City" (Gad is one of the TEN Hebrew / Israelite Tribes who are NOT Jewish). This name was later changed by the Romans (formerly of Babylon) to "Gades" (pronounced GADIZ) and now it is known as CADIZ.
Therefore Iberia belongs, RIGHTFULLY, to the (British/Israel) HEBREWS whose name it bears.
"And God said unto Jacob - now called ISRAEL ..... A NATION AND A 'COMPANY' OF NATIONS (a 'Commonwealth' of nations) shall be of thee, and kings shall come out of thy loins" - Genesis 32:28; 35:11.
Central Iberia was invaded by the Romans; Vandals and others and these invaders drove the majority of the Hebrews out, to BRITAIN (from where they spread West to America; East to India and Australasia; North to Canada and South to Africa, in exactly the order prophesied by God in Genesis 28 v 14), leaving only a few Hebrews along the Northern; Western and Southern coast-lands :-
Vizcaya and Galicia in the North; Costa de la Luz (Light) in the West and The Camp of Gibraltar in the South.
That is WHY the Basques and Galicians want independence from the rest of Spain because they are from a totally different race, being descended from Hebrews, not from Romans (formerly Babylonians) or Vandals.
The Vandals invaded Southern Iberia and named it Vandalucia (Andalucia today), however the land itself is still known today as Iberia - "The HEBREW's Land", NOT Vandal's or Roman's land or Spaniard's land.
Therefore the Spanish people, who are not Hebrews, are NOT the RIGHTFUL possessors of Iberia - the Hebrews are (not Jews).
Now let us analyse the Gibraltarian side of the argument.
The word BRIT-ISH is Hebrew and it means "the people of the Covenant", in other words "the People Israel" - ALL of whom are HEBREWS (NOT Jews).
The reason that so many British people have bought homes in Iberia and have visited Iberia on holidays, for years, billions of them, including me, is because it was once, like Israel before it, their homeland and many would like to make it so again, if they could afford to live there.
Now let us "come to the point" about GIBRALTAR, whose very FIRST inhabitants (since the birth of Adam) were British from the Hebrew, Israelite Tribes of Gad; Dan(ish) and Simeon during the reign of king Solomon in 1000 B.C. - I repeat - 1000 B.C., at the very latest. Solomon was the son of king David, the shepherd boy, who slew Goliath and became king of Israel; and from whom Elizabeth the Second is directly descended.
King Solomon sent his famous miners to his Iberian Peninsula to mine for him and to return, by ship from Gibraltar, the minerals, to increase his legendary wealth. The legendary "King Solomon's Mines."
There is a tomb-stone in Sagunto, Spain, bearing the epitaph, in HEBREW, "This is the tomb of Adoniram (1 kings 4:6), an officer of Solomon, who came to collect Tribute (taxes) and died the (illegible) day." Tribute (tax) is only collected from subjects not foreigners.
The Tribal Standard (flag) of GAD is a CAMP (military TROOP encampment - FORT or CASTLE - Genesis 49 v 19 and the Jewish Encyclopedia) and the Tribe of Gad populated Southern Iberia; at least as far North as GADIZ; including GIBRALTAR which today bears what seems quite a strange name "The CAMP of Gibraltar" and the modern-day Tribal Standard (Flag) of Gibraltar is a military CAMP - FORTRESS - CASTLE.
