'Ashes' in the Bible

They will remove the fat-soaked ashes from the altar and spread a purple cloth over it;

A clean man will gather the ashes of the heifer, and he will put [them] in a clean {place outside the camp}; it will be for the community of the {Israelites} as a requirement for waters of impurity; it [is] a purification [offering].

The one who gathers the ashes of the heifer will wash his garments; he will be unclean until evening. It will be an eternal decree for the {Israelites} and for one who dwells as an alien in their midst.
