FOR BEHOLD,... in those days and at that time when I shall reverse the captivity and restore the fortunes of Judah and Jerusalem, I will gather all nations and will bring them down into the Valley of Jehoshaphat, and there will I deal with and execute judgment upon them for their treatment of My people and of My heritage Israel, whom they have scattered among the nations and...” because they have divided MY LAND.” ...Joel 3:1-2
God is clear in that verse
‘My’ people
‘My’ heritage Israel
‘My’ Land
