اَلْعَدَد 4:23

مِنِ ٱبْنِ ثَلَاثِينَ سَنَةً فَصَاعِدًا إِلَى ٱبْنِ خَمْسِينَ سَنَةً تَعُدُّهُمْ، كُلَّ ٱلدَّاخِلِينَ لِيَتَجَنَّدُوا أَجْنَادًا، لِيَخْدِمُوا خِدْمَةً فِي خَيْمَةِ ٱلِٱجْتِمَاعِ.

From thirty years old and upward until fifty years old shalt thou number them; all that enter in to perform the service, to do the work in the tabernacle of the congregation.
