اَلْعَدَد 19:21

فَتَكُونُ لَهُمْ فَرِيضَةً دَهْرِيَّةً. وَٱلَّذِي رَشَّ مَاءَ ٱلنَّجَاسَةِ يَغْسِلُ ثِيَابَهُ، وَٱلَّذِي مَسَّ مَاءَ ٱلنَّجَاسَةِ يَكُونُ نَجِسًا إِلَى ٱلْمَسَاءِ.

And it shall be a perpetual statute unto them, that he that sprinkleth the water of separation shall wash his clothes; and he that toucheth the water of separation shall be unclean until even.
