اَلْعَدَد 8:7

وَهَكَذَا تَفْعَلُ لَهُمْ لِتَطْهِيرِهِمِ: ٱنْضِحْ عَلَيْهِمْ مَاءَ ٱلْخَطِيَّةِ، وَلْيُمِرُّوا مُوسَى عَلَى كُلِّ بَشَرِهِمْ، وَيَغْسِلُوا ثِيَابَهُمْ فَيَتَطَهَّرُوا.

And thus shalt thou do unto them, to cleanse them: Sprinkle water of purifying upon them, and let them shave all their flesh, and let them wash their clothes, and so make themselves clean.
