Abraham, Sarah and Isaac / Sara'a maid Hagar the Egyptian and Ishmael

Gen. 17:18 And Abraham said unto God, O that Ishmael might live before thee!
[19] And God said, Sarah thy wife shall bear thee a son indeed; and thou shalt call his name Isaac: and I will establish my covenant with him for an everlasting covenant, and with his seed after him.
[20] And as for Ishmael, I have heard thee: Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly; twelve princes shall he beget, and I will make him a great nation.
[21] But my covenant will I establish with Isaac, which Sarah shall bear unto thee at this set time in the next year.

Gen.21 [9] And Sarah saw the son of Hagar the Egyptian, which she had born unto Abraham, mocking.
[10] Wherefore she said unto Abraham, Cast out this bondwoman and her son: for the son of this bondwoman shall not be heir with my son, even with Isaac.
[11] And the thing was very grievous in Abraham's sight because of his son.
[12] And God said unto Abraham, Let it not be grievous in thy sight because of the lad, and because of thy bondwoman; in all that Sarah hath said unto thee, hearken unto her voice; for in Isaac shall thy seed be called.

[13] And also of the son of the bondwoman will I make a nation, because he is thy seed.

Rom.9 [6] Not as though the word of God hath taken none effect. For they are not all Israel, which are of Israel:

[7] Neither, because they are the seed of Abraham, are they all children: but, In Isaac shall thy seed be called.

[8] That is, They which are the children of the flesh, these are not the children of God: but the children of the promise are counted for the seed.

Gal.4[22] For it is written, that Abraham had two sons, the one by a bondmaid, the other by a freewoman.
[23] But he who was of the bondwoman was born after the flesh; but he of the freewoman was by promise.
[24] Which things are an allegory: for these are the two covenants; the one from the mount Sinai, which gendereth to bondage, which is Agar.
[25] For this Agar is mount Sinai in Arabia, and answereth to Jerusalem which now is, and is in bondage with her children.
[26] But Jerusalem which is above is free, which is the mother of us all.
[27] For it is written, Rejoice, thou barren that bearest not; break forth and cry, thou that travailest not: for the desolate hath many more children than she which hath an husband.
[28] Now we, brethren, as Isaac was, are the children of promise.
[29] But as then he that was born after the flesh persecuted him that was born after the Spirit, even so it is now.
[30] Nevertheless what saith the scripture? Cast out the bondwoman and her son: for the son of the bondwoman shall not be heir with the son of the freewoman.
[31] So then, brethren, we are not children of the bondwoman, but of the free.

The Land Of Israel

[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,

[2] And all Naphtali, and the land of Ephraim, and Manasseh, and all the land of Judah, unto the utmost sea,

[3] And the south, and the plain of the valley of Jericho, the city of palm trees, unto Zoar.

[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.

Num.34:[1] And the LORD spake unto Moses, saying,
[2] Command the children of Israel, and say unto them, When ye come into the land of Canaan; (this is the land that shall fall unto you for an inheritance, even the land of Canaan with the coasts thereof:)
[3] Then your south quarter shall be from the wilderness of Zin along by the coast of Edom, and your south border shall be the outmost coast of the salt sea eastward:
[4] And your border shall turn from the south to the ascent of Akrabbim, and pass on to Zin: and the going forth thereof shall be from the south to Kadesh-barnea, and shall go on to Hazar-addar, and pass on to Azmon:
[5] And the border shall fetch a compass from Azmon unto the river of Egypt, and the goings out of it shall be at the sea.
[6] And as for the western border, ye shall even have the great sea for a border: this shall be your west border.
[7] And this shall be your north border: from the great sea ye shall point out for you mount Hor:
[8] From mount Hor ye shall point out your border unto the entrance of Hamath; and the goings forth of the border shall be to Zedad:
[9] And the border shall go on to Ziphron, and the goings out of it shall be at Hazar-enan: this shall be your north border.
[10] And ye shall point out your east border from Hazar-enan to Shepham:
[11] And the coast shall go down from Shepham to Riblah, on the east side of Ain; and the border shall descend, and shall reach unto the side of the sea of Chinnereth eastward:
[12] And the border shall go down to Jordan, and the goings out of it shall be at the salt sea: this shall be your land with the coasts thereof round about.

Exod. 23:[30] By little and little I will drive them out from before thee, until thou be increased, and inherit the land.[31] And I will set thy bounds from the Red sea even unto the sea of the Philistines, and from the desert unto the river: for I will deliver the inhabitants of the land into your hand; and thou shalt drive them out before thee.
[32] Thou shalt make no covenant with them, nor with their gods.
[33] They shall not dwell in thy land, lest they make thee sin against me: for if thou serve their gods, it will surely be a snare 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:[19] The Kenites, and the Kenizzites, and the Kadmonites,
[20] And the Hittites, and the Perizzites, and the Rephaims,
[21] And the Amorites, and the Canaanites, and the Girgashites, and the Jebusites.

If we take Scripture literally; then we must come to the conclusion that the nation of Israel is one country and that Judea and Samaria, the West Bank, is part of Israel-deeded by God to the descendants of Abraham, Isaac and Jacob.

Josh.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,
[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.
[3] Every place that the sole of your foot shall tread upon, that have I given unto you, as I said unto Moses.
[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.

Read all of Lev. 25

Lev. 25:23 The land shall not be sold for ever: the land is mine; for ye are strangers and sojourners with me.

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:
[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:
[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.
[4] So Abram departed, as the LORD had spoken unto him; and Lot went with him: and Abram was seventy and five years old when he departed out of Haran.
[5] And Abram took Sarai his wife, and Lot his brother's son, and all their substance that they had gathered, and the souls that they had gotten in Haran; and they went forth to go into the land of Canaan; and into the land of Canaan they came.
[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.
[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:
[15] For all the land which thou seest, to thee will I give it, and to thy seed for ever.
[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.
[17] Arise, walk through the land in the length of it and in the breadth of it; for I will give it unto thee.
[18] Then Abram removed his tent, and came and dwelt in the plain of Mamre, which is in Hebron, and built there an altar unto the LORD.

Gen.24[7] The LORD God of heaven, which took me from my father's house, and from the land of my kindred, and which spake unto me, and that sware unto me, saying, Unto thy seed will I give this land; he shall send his angel before thee, and thou shalt take a wife unto my son from thence.

Gen.28[13] And, behold, the LORD stood above it, and said, I am the LORD God of Abraham thy father, and the God of Isaac: the land whereon thou liest, to thee will I give it, and to thy seed;

Gen.35[12] And the land which I gave Abraham and Isaac, to thee I will give it, and to thy seed after thee will I give the land.

Exod.33[1] And the LORD said unto Moses, Depart, and go up hence, thou and the people which thou hast brought up out of the land of Egypt, unto the land which I sware unto Abraham, to Isaac, and to Jacob, saying, Unto thy seed will I give it:
