'Dust' in the Bible

Give no word of it in Gath, let there be no weeping at all: at Beth-le-aphrah be rolling in the dust.

And my hater will see it and be covered with shame; she who said to me, Where is the Lord your God? my eyes will see their desire effected on her, now she will be crushed under foot like the dust of the streets.

They will take dust as their food like a snake, like the things which go flat on the earth; they will come shaking with fear out of their secret places: they will come with fear to the Lord our God, full of fear because of you.
