fine, wind-blown dust: the airborne powder a force stirs up, scatters, or makes settle
This is the word for the fine, flying kind of dust, the visible cloud that wind, feet, or hooves throw into the air. Hebrew keeps it distinct from the ordinary word for dust as soil and ground, the stuff underfoot that a person is formed from and returns to at death (עָפָר). English blurs the two into one word, "dust," but this term always points to particles so fine and light that they hang and drift rather than lie still.
Across its handful of appearances the word does one thing, name airborne dust in motion, and it does so in three recognizable ways:
- as a real substance that spreads through the air and settles or falls (the soot that becomes a plague, the sky that rains down powder instead of water)
- as a picture of something scattered until nothing solid is left (a blossom that goes up as dust, an enemy army reduced to specks)
- as the cloud a power kicks up when it moves (the dust of a war-horse charge, and the storm-clouds that are only the dust of God's own feet)
What ties these together is a single pattern that runs through every use: this dust shows up only where God is acting. It is either the fine powder into which God grinds down the wicked, or the cloud that rises around God's own approach. The same image can terrify or exalt, but it is never idle household dust; it is dust made visible by a force on the move.
