'Ashes' in the Bible

“They are to remove the ashes from the bronze altar, spread a purple cloth over it,

“A man who is clean is to gather up the cow’s ashes and deposit them outside the camp in a ceremonially clean place. The ashes must be kept by the Israelite community for preparing the water to remove impurity; it is a sin offering.

Then the one who gathers up the cow’s ashes must wash his clothes, and he will remain unclean until evening. This is a permanent statute for the Israelites and for the foreigner who resides among them.

For the purification of the unclean person, they are to take some of the ashes of the burnt sin offering, put them in a jar, and add fresh water to them.
