اَلتَّثْنِيَة 21:17

بَلْ يَعْرِفُ ٱبْنَ ٱلْمَكْرُوهَةِ بِكْرًا لِيُعْطِيَهُ نَصِيبَ ٱثْنَيْنِ مِنْ كُلِّ مَا يُوجَدُ عِنْدَهُ، لِأَنَّهُ هُوَ أَوَّلُ قُدْرَتِهِ. لَهُ حَقُّ ٱلْبَكُورِيَّةِ.

But he shall acknowledge the son of the hated for the firstborn, by giving him a double portion of all that he hath: for he is the beginning of his strength; the right of the firstborn is his.
