Ashes

The ashes on the altar of burnt offering were gathered into a cavity in its surface. The ashes of a red heifer burnt entire, according to regulations prescribed in Numb. 19, had the ceremonial efficacy of purifying the unclean, (Hebrews 9:13) but of polluting the clean. [Sacrifice] Ashes about the person, especially on the head, were used as a sign of sorrow. [Mourning]
