'Dust of the Earth' in the Bible

I will make your offspring like the dust of the earth, so that if anyone could count the dust of the earth, then your offspring could be counted.

Your offspring will be like the dust of the earth, and you will spread out toward the west, the east, the north, and the south. All the peoples on earth will be blessed through you and your offspring.

Then the Lord said to Moses, “Tell Aaron: Stretch out your staff and strike the dust of the earth, and it will become gnats throughout the land of Egypt.”

And they did this. Aaron stretched out his hand with his staff, and when he struck the dust of the earth, gnats were on man and beast. All the dust of the earth became gnats throughout the land of Egypt.

I pulverize them like dust of the earth;I crush them and trample them like mud in the streets.

Lord God, let Your promise to my father David now come true. For You 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 handor marked off the heavens with the span of his hand?Who has gathered the dust of the earth in a measureor weighed the mountains in a balanceand the hills in the scales?

Many of those who sleep in the dustof the earth will awake,some to eternal life,and some to shame and eternal contempt.
