Page "Manna" Paragraph 17

Manna is from Heaven, according to the Bible, but the various identifications of manna are naturalistic.

In the Mishnah, manna is treated as a supernatural substance, created during the twilight of the sixth day of Creation, and ensured to be clean, before it arrives, by the sweeping of the ground by a northern wind and subsequent rains.

According to classical rabbinical literature, manna was ground in a heavenly mill for the use of the righteous, but some of it was allocated to the wicked and left for them to grind themselves.
