'Ash' in the Bible

all the rest of the bull -- he must bring outside the camp to a ceremonially clean place, to the fatty ash pile, and he must burn it on a wood fire; it must be burned on the fatty ash pile.

He lifts the weak from the dust; he raises the poor from the ash heap to seat them with princes and to bestow on them an honored position. The foundations of the earth belong to the Lord, and he has placed the world on them.
