Future Borders of Israel are given in Numbers 34:1.

And the LORD* spoke to Moses saying, 2. “Command the children of Israel and say to them,

“‘When you come into the land of Canaan, this is the land that will fall to you for an inheritance, the land of Canaan according to its borders. 3. Then your south side will be from the wilderness of Zin along by the border of Edom and your south border will be the outermost end of the Salt Sea eastward, 4. and your border will turn from the south to the ascent of Akrabbim and pass on to Zin and from there it will be from the south to Kadesh Barnea, and will go on to Hazaraddar and pass on to Azmonah. 5. And the border will turn about from Azmonah to the river of Egypt, and from there it will go to the sea. 6. And as the western border, you will even have the Great Sea for a border: this will be your west border. 7. And this will be your north border, from the Great Sea you will point out for yourselves Mount Hor, 8. from Mount Hor you will point out to the entrance of Hamat, and from there the border will be to Zedadah, 9. and the border will go on to Ziphronah, and from there it will be at Hazar-Enan: this will be your north border. 10. And you will point out your east border from Hazar-Enan to Shefamah, 11. and the border will go down from Shefamah to Riblah, on the east side of Ayin, and the border will descend and will reach to the side of the lake of Kinneret eastward 12. and the border will go down to the Jordan, and from there it will go to the Salt Sea: this will be your land according to its borders all around.’”
