اَلْعَدَد 8:17

لِأَنَّ لِي كُلَّ بِكْرٍ فِي بَنِي إِسْرَائِيلَ مِنَ ٱلنَّاسِ وَمِنَ ٱلْبَهَائِمِ. يَوْمَ ضَرَبْتُ كُلَّ بِكْرٍ فِي أَرْضِ مِصْرَ قَدَّسْتُهُمْ لِي.

For all the firstborn of the children of Israel are mine, both man and beast: on the day that I smote every firstborn in the land of Egypt I sanctified them for myself.
