'Dust' in the Bible

And the priest will take holy water in a pot and put in it dust from the floor of the House;

And your children will be wanderers in the waste land for forty years, undergoing punishment for your false ways, till your bodies become dust in the waste land.

Then let a man who is clean take the dust of the burned cow and put it outside the tent-circle in a clean place, where it is to be kept for the children of Israel and used in making the water which takes away what is unclean: it is a sin-offering.

And he who takes up the dust of the burned cow is to have his clothing washed with water and be unclean till evening: this is to be a law for ever, for the children of Israel as well as for the man from another country who is living among them.

And for the unclean, they are to take the dust of the burning of the sin-offering, and put flowing water on it in a vessel:

Who is able to take the measure of the dust of Jacob or the number of the thousands of Israel? May my death be the death of the upright and my last end like his!
