Land Promise
The land promise for Israel is the term used to say that the people of Israel, the Jews, have a right to the country of Israel.
Borders
The borders are given in several chapters in the Bible, mainly:
Joshua 13-21: This land is only fully taken in the time of David and Solomon (TODO add refs)
Numbers 34: TODO, ^^
Ezekiel 47: The border that will be in the future.
