اَلْعَدَد 4:3

مِنِ ٱبْنِ ثَلَاثِينَ سَنَةً فَصَاعِدًا إِلَى ٱبْنِ خَمْسِينَ سَنَةً، كُلِّ دَاخِلٍ فِي ٱلْجُنْدِ لِيَعْمَلَ عَمَلًا فِي خَيْمَةِ ٱلِٱجْتِمَاعِ.

From thirty years old and upward even until fifty years old, all that enter into the host, to do the work in the tabernacle of the congregation.
