Look what God states regarding Covenant Isreal....
Leviticus 25:23
23 “‘The land must not be sold permanently, because the land is mine and you reside in my land as foreigners and strangers. 24 Throughout the land that you hold as a possession, you must provide for the redemption of the land.
And then later in Chapter 26
14 “‘But if you will not listen to me and carry out all these commands,
15 and if you reject my decrees and abhor my laws and fail to carry out all my commands and so violate my covenant,
16 then I will do this to you: I will bring on you sudden terror, wasting diseases and fever that will destroy your sight and sap your strength. You will plant seed in vain, because your enemies will eat it.
Apart from Covenant faithfulness to Torah, not the later rabbinical teachings no Israelite had any claim to the land.
