اَلْعَدَد 36:9

فَلَا يَتَحَوَّلْ نَصِيبٌ مِنْ سِبْطٍ إِلَى سِبْطٍ آخَرَ، بَلْ يُلَازِمُ أَسْبَاطُ بَنِي إِسْرَائِيلَ كُلُّ وَاحِدٍ نَصِيبَهُ».

Neither shall the inheritance remove from one tribe to another tribe; but every one of the tribes of the children of Israel shall keep himself to his own inheritance.
