Exodus 16:14

When the dew was gone, thin flakes like frost on the ground appeared on the desert floor.

(New International Version)

When the layer of dew evaporated, behold, on the surface of the wilderness there was a fine flake-like thing, fine as the frost on the ground.

(New American Standard Bible)

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.

(King James Version)
