'Dust of the Earth' in the Bible

I will make your descendants like the dust of the earth which, if anyone were able to count the dust of the earth, your descendants would be [so] counted.

Your descendants shall be like the dust of the earth, and you will spread out to the west, and to the east, and to the north and to the south. And all the families of the earth will be blessed through you and through your descendants.

I beat them fine, like the dust of the earth; like the mire of the streets, I crushed them, I stamped them down.

Now, O Yahweh God, let your word to David my father be fulfilled, for you yourself have made me king over a people as numerous as the dust of the earth.

Who has measured [the] waters in the hollow of his hand and marked off [the] heavens with span, comprehended the dust of the earth in third of a measure and weighed out [the] mountains in the scales, and [the] hills in a balance?
