Wikipedia says Dust are fine particles of matter. It generally consists of particles in the atmosphere that come from various sources such as soil, dust lifted by weather (an aeolian process), volcanic eruptions, and pollution. Dust in homes, offices, and other human environments contains small amounts of plant pollen, human and animal hairs, textile fibers, paper fibers, minerals from outdoor soil, human skin cells, burnt meteorite particles, and many other materials which may be found in the local environment.
Fugitive dust falling on the just and unjust alike
Falling on all creation
Falling on the whole world
Stuff of stars
Convulsions of the earth
Cast high in the air and blown around the world.
You and I made of stardust from the heart of the supernova, warmed by the heat of many suns
Made incarnate in the world
We are all the same
King or beggar
Refugee or conqueror
On the up
On the down
Just staying still
One beating heart
with the one great rhythm
of the one great song
Lord help us to love ourselves and others as one and the same
9 Then you shall call, and the Lord will answer;
you shall cry for help, and he will say, Here I am.
If you remove the yoke from among you,
the pointing of the finger, the speaking of evil,
10 if you offer your food to the hungry
and satisfy the needs of the afflicted,
then your light shall rise in the darkness
and your gloom be like the noonday.
11 The Lord will guide you continually,
and satisfy your needs in parched places,
and make your bones strong;
and you shall be like a watered garden,
like a spring of water,
whose waters never fail.
12 Your ancient ruins shall be rebuilt;
you shall raise up the foundations of many generations;
you shall be called the repairer of the breach,
the restorer of streets to live in.
13 If you refrain from trampling the sabbath,
from pursuing your own interests on my holy day;
if you call the sabbath a delight
and the holy day of the Lord honourable;
if you honour it, not going your own ways,
serving your own interests, or pursuing your own affairs;
14 then you shall take delight in the Lord,
and I will make you ride upon the heights of the earth;
I will feed you with the heritage of your ancestor Jacob,
for the mouth of the Lord has spoken.
