Numbers 31:23

凡能见火的，你们要叫它经火就为洁净，然而还要用除污秽的水洁净它；凡不能见火的，你们要叫它过水。

fán néng jiàn huǒ de ， nǐ men yào jiào tā jīng huǒ jiù wèi jié jìng ， rán ér hái yào yòng chú wū huì de shuǐ jié jìng tā ； fán bù néng jiàn huǒ de ， nǐ men yào jiào tā guò shuǐ 。

everything that may withstand the fire, you shall make to go through the fire, and it shall be clean; nevertheless it shall be purified with the water for impurity. All that doesn’t withstand the fire you shall make to go through the water.
