Palestine is NOT a biblical word. You won't find it anywhere in the Bible except as a label on maps in the back of the Bible.
What came to be so called Palestine was the land of Israel for over 1,500 years....the period of the biblical judges and kings. The land did not become known as Palestine until after the Romans destroyed Jerusalem in AD and began to disperse the Jewish people worldwide.
The Word Palestine is derived from the Roman word Philistines, So to humiliate the Jewish people, the Romans renamed the land after their enemy.
The Biblical Right to the Land. The God of the Jewish people is the One who created the universe, and Psalm 24:1 He owns all of it, He therefore has the right to give any part of this earth to whomever He pleased.
It pleased God to give a large section of the Middle East to the Jewish people. This gift occurred 4,000 years ago when God appeared to Abraham and gave him and his descendants a land grant stretching from the Mediterranean Sea to the Euphrates River. (Genesis 15:18. This land grant has never full been realized, but will be during the Millennial reign of Jesus. A small portion of this grant is what is currently referred to as Palestine. At the time that Abraham was promised the land, the area was called "The Land of Canaan."
Satan is now orchestrating all the nations of the world to come against the nation of Israel thru the perpetration of myths concerning the Jewish people and their nation.
Paradoxically, in the process, Satan is fulfilling Bible prophecy for the Prophet Zechariah who states 2,500 years ago that in the end times the whole world would come against Israel. Zechariah 12:2-3.
This whole situation is going to be resolved in Ezekiel 38 and 39.
Psalm 105:1,8-11. Oh Give thanks to the Lord....for He has remembered His covenant forever. The covenant which He made with Abraham, and His oath to Isaac, Then He confirmed it to Jacob....and to Israel an everlasting covenant, Saying, "To you I will give the land of Canaan as the portion of your inheritance."
The First covenant was a Land Title through Abraham, It was unconditional. The second title was a Land Use Covenant given through Moses. It was also unconditional. In 1947, the United Nations officially and legally authorized the creation of the modern state of Israel.
The Arabs refused to accept the UN action and resorted to war. No one can truthfully claim that the Jews have no right to the land. It belongs to them both biblically and legally.
Know the truth and speak up for it. It is the Will of God, Hashem.
