Hebrew for, perhaps, ‘what is it?’; the food which sustained the Israelites during their trek through the wilderness. It was lying on the ground (Exod. 16: 13 ff.), white in colour and sweet in taste. On Fridays a double portion fell (Exod. 16: 22–6) to avoid breaking the Sabbath by working, to accord with the Priestly editor's insistence on Sabbath observance (Exod. 20: 8–11). An explanation of this food is that it was sap expelled by insects which turned into a kind of dew with a taste resembling honey or the cocoon of the parasitic beetle Trehala manna. Its presence is described as a miracle (Deut. 8: 3). Jesus refers to manna in his discourse about the bread of life (John 6: 31–2) and it is mentioned as food for believers in the new age in Rev. 2: 17.
