'Dust' in the Bible

Now, O LORD God, let thy promise unto David my father be established: for thou hast made me king over a people like the dust of the earth in multitude.

And also Maacah, the mother of Asa the king, he removed from being queen, because she had made an abominable image for an Asherah; and Asa cut down her image, and made dust of it, and burnt it at the brook Kidron.

And they brake down the altars of Baalim in his presence; and the images, that were on high above them, he cut down; and the groves, and the carved images, and the molten images, he brake in pieces, and made dust of them, and strowed it upon the graves of them that had sacrificed unto them.

he also tore down altars, destroyed the Asherim and the carved images, grinding them into dust, and chopped down all the incense altars throughout the land of Israel. Then he went back to Jerusalem.
