Reference for manna/mana:
Manna/Mana or Flowering Ash
Manna

Manna is the name of the food miraculously produced for the Israelites in the desert in the book of Exodus.
The modern material known as manna is a secretion from certain desert or semi-desert shrubs. The material is produced by sap-sucking insects that secrete a honeydew like liquid, that when dried forms manna; manna has a sweet taste, and eaten in large quantities is mildly laxative.



There is a material meaning and a spiritual meaning for the word making up the Biblical "manna".

I realize this is a very old post..but I'm new...and cannot make my own thread yet. So I went into the search box and typed in "hoar frost" to see if there were any threads on it already...I found one...this one...speaking of manna. Which is exactly where I was going with it. I was sitting here this morning, looking out my window, I live in ga, and its cold, there is frost. And I was reading my bible....I'm in Exodus, right at the part where Manna is rained down. And it hit me.....it spoke of dew being on the ground, and when the dew cleared...they found the manna..it looked like hoar frost. So two things came to me...how in the world was there dew in the desert? what did it cling to? the sand? and how did the israelites know what hoar frost was? I mean..first of all..why didn't they just call it "frost" ? but specifically "hoar" frost? and where in the world would they have seen "frost" to begin with? I realize the weather may have been very different then..but the author of this particular piece states "desert" and then dew and frost? but more specifically "hoar" frost. So on a path, I looked up "hoar frost" and came across this:

Hoar frost is a radiation frost.
Radiation frost (also called hoar frost or hoarfrost) refers to the white ice crystals, loosely deposited on the ground or exposed objects, that form on cold clear nights when heat losses into the open skies cause objects to become colder than the surrounding air. A related effect is flood frost which occurs when air cooled by ground-level radiation losses travels downhill to form pockets of very cold air in depressions, valleys, and hollows. Hoar frost can form in these areas even when the air temperature a few feet above ground is well above freezing. Nonetheless the frost itself will be at or below the freezing temperature of water.
Hoar frost may have different names depending on where it forms. For example, air hoar is a deposit of hoar frost on objects above the surface, such as tree branches, plant stems, wires; surface hoar is formed by fernlike ice crystals directly deposited on snow, ice or already frozen surfaces; crevasse hoar consists in crystals that form in glacial crevasses where water vapour can accumulate under calm weather conditions; depth hoar refers to cup shaped, faceted crystals formed within dry snow, beneath the surface.
Surface hoar is a cause of avalanches when it forms on top of snow. Conditions that are ideal are cold clear nights, with a very light wind that is able to circulate more humidified air around the snow surface. Wind that is too abrupt will destroy the crystals. When buried by subsequent snows they may remain standing for easy identification, or become laid down, but still dangerous because of the weakness of the crystals
Hoar frost also occurs around man-made environments such as freezers or industrial cold storage facilities. It occurs in adjacent rooms that are not well insulated against the cold or around entry locations where humidity and moisture will enter and freeze instantly depending on the freezer temperature.

just wondering if anyone could shed more info...would they have seen frost in egypt? in the desert to even know to call it that?
