We remember the fish, which we did eat in Egypt freely; the
cucumbers, and the melons, and the leeks, and the onions, and the garlic: But now our soul is dried away: there is nothing at all, beside this manna, before our eyes. And the manna was as coriander seed, and the color thereof as the color of bdellium. Numbers 11:5-7
Coriander, Coriandrum sativum L., is in the carrot family and has leaves like parsley, Petroselinumcrispum (Mill.) Nyman ex A.W. Hill, but the seeds are gray and round about like peppercorns and are used as a culinary spice. The only other mention of coriander is also as a description of manna in Exodus 16:31.
Bdellium is an aromatic gum that is described as becoming transparent, wax like, and appearing similar to a pearl when it hardens. The source of bdellium is reported to come from Commiphoraafricana (A. Rich.) Engl., and/or Commiphorawightii (Arn.) Bhandari both of which are trees related to Commiphoramyrrha (Nees) Engl., the source of myrrh. The only other reference to bdellium is in Genesis 2:12 where it mentions an area where bdellium is found relative to the location of the Garden of Eden thus favoring the later source.
Tilapia is the primary type of fish mentioned for consumption from the river in Egypt to the Sea of Galilee
