Whose Land is it

Gen 12:1 Now the LORD had said unto Abram, Get thee out of thy country, and from thy kindred, and from thy father's house, unto a land that I will shew thee:
Gen 12:2 And I will make of thee a great nation, and I will bless thee, and make thy name great; and thou shalt be a blessing:
Gen 12:3 And I will bless them that bless thee, and curse him that curseth thee: and in thee shall all families of the earth be blessed.

Gen 12:6 And Abram passed through the land unto the place of Sichem, unto the plain of Moreh. And the Canaanite [was] then in the land.
Gen 12:7 And the LORD appeared unto Abram, and said, Unto thy seed will I give this land: and there builded he an altar unto the LORD, who appeared unto him.

Gen 13:14 And the LORD said unto Abram, after that Lot was separated from him, Lift up now thine eyes, and look from the place where thou art northward, and southward, and eastward, and westward:
Gen 13:15 For all the land which thou seest, to thee will I give it, and to thy seed for ever.
Gen 13:16 And I will make thy seed as the dust of the earth: so that if a man can number the dust of the earth, [then] shall thy seed also be numbered.
Gen 13:17 Arise, walk through the land in the length of it and in the breadth of it; for I will give it unto thee.

Gen 15:18 In the same day the LORD made a covenant with Abram, saying, Unto thy seed have I given this land, from the river of Egypt unto the great river, the river Euphrates:
Gen 15:19 The Kenites, and the Kenizzites, and the Kadmonites,
Gen 15:20 And the Hittites, and the Perizzites, and the Rephaims,
Gen 15:21 And the Amorites, and the Canaanites, and the Girgashites, and the Jebusites.

God had confirmed His promise to:

- Isaac:

Gen 26:2 And the LORD appeared unto him, and said, Go not down into Egypt; dwell in the land which I shall tell thee of:
Gen 26:3 Sojourn in this land, and I will be with thee, and will bless thee; for unto thee, and unto thy seed, I will give all these countries, and I will perform the oath which I sware unto Abraham thy father;
Gen 26:4 And I will make thy seed to multiply as the stars of heaven, and will give unto thy seed all these countries; and in thy seed shall all the nations of the earth be blessed;
Gen 26:5 Because that Abraham obeyed my voice, and kept my charge, my commandments, my statutes, and my laws.

Deut 34:1 And Moses went up from the plains of Moab unto the mountain of Nebo, to the top of Pisgah, that [is] over against Jericho. And the LORD shewed him all the land of Gilead, unto Dan,
Deut 34:2 And all Naphtali, and the land of Ephraim, and Manasseh, and all the land of Judah, unto the utmost sea,
Deut 34:3 And the south, and the plain of the valley of Jericho, the city of palm trees, unto Zoar.
Deut 34:4 And the LORD said unto him, This [is] the land which I sware unto Abraham, unto Isaac, and unto Jacob, saying, I will give it unto thy seed: I have caused thee to see [it] with thine eyes, but thou shalt not go over thither.

Later God addressed to Joshua:

Joshua 1:1 Now after the death of Moses the servant of the LORD it came to pass, that the LORD spake unto Joshua the son of Nun, Moses' minister, saying,
Joshua 1:2 Moses my servant is dead; now therefore arise, go over this Jordan, thou, and all this people, unto the land which I do give to them, [even] to the children of Israel.
Joshua 1:3 Every place that the sole of your foot shall tread upon, that have I given unto you, as I said unto Moses.
Joshua 1:4 From the wilderness and this Lebanon even unto the great river, the river Euphrates, all the land of the Hittites, and unto the great sea toward the going down of the sun, shall be your coast.
Joshua 1:5 There shall not any man be able to stand before thee all the days of thy life: as I was with Moses, [so] I will be with thee: I will not fail thee, nor forsake thee.
Joshua 1:6 Be strong and of a good courage: for unto this people shalt thou divide for an inheritance the land, which I sware unto their fathers to give them.

Joshua had received the Promised Land:

Joshua 11:19 There was not a city that made peace with the children of Israel, save the Hivites the inhabitants of Gibeon: all [other] they took in battle.
Joshua 11:20 For it was of the LORD to harden their hearts, that they should come against Israel in battle, that he might destroy them utterly, [and] that they might have no favour, but that he might destroy them, as the LORD commanded Moses.

Joshua 11:23 So Joshua took the whole land, according to all that the LORD said unto Moses; and Joshua gave it for an inheritance unto Israel according to their divisions by their tribes. And the land rested from war.

Israeli land had been given to Israel. None else haven't right for it!
