اَلْعَدَد 25:13

فَيَكُونُ لَهُ وَلِنَسْلِهِ مِنْ بَعْدِهِ مِيثَاقَ كَهَنُوتٍ أَبَدِيٍّ، لِأَجْلِ أَنَّهُ غَارَ لِلهِ وَكَفَّرَ عَنْ بَنِي إِسْرَائِيلَ».

And he shall have it, and his seed after him, even the covenant of an everlasting priesthood; because he was zealous for his God, and made an atonement for the children of Israel.
