'Ashes' in the Bible

Then the priest must remove its entrails by cutting off its tail feathers, and throw them to the east side of the altar into the place of fatty ashes,

Then the priest must put on his linen robe and must put linen leggings over his bare flesh, and he must take up the fatty ashes of the burnt offering that the fire consumed on the altar, and he must place them beside the altar.

Then he must take off his clothes and put on other clothes, and he must bring the fatty ashes outside the camp to a ceremonially clean place,
