When the layer of dew had evaporated, there were thin flakes on the desert floor, as fine as frost on the ground.
KJV
And when the dew that lay was gone up, behold, upon the face of the wilderness [there lay] a small round thing, [as] small as the hoar frost on the ground.
ASV
And when the dew that lay was gone up, behold, upon the face of the wilderness a small round thing, small as the hoar-frost on the ground.
