اَلْعَدَد 31:23

كُلُّ مَا يَدْخُلُ ٱلنَّارَ، تُجِيزُونَهُ فِي ٱلنَّارِ فَيَكُونُ طَاهِرًا، غَيْرَ أَنَّهُ يَتَطَهَّرُ بِمَاءِ ٱلنَّجَاسَةِ. وَأَمَّا كُلُّ مَا لَا يَدْخُلُ ٱلنَّارَ فَتُجِيزُونَهُ فِي ٱلْمَاءِ.

Every thing that may abide the fire, ye shall make it go through the fire, and it shall be clean: nevertheless it shall be purified with the water of separation: and all that abideth not the fire ye shall make go through the water.
