I recently read that following verse in Numbers 11.5, 'Bamidbar': "We remember the fish that we ate in Egypt free of charge, the cucumbers, the watermelons, the leeks, the onions, and the garlic" (found on chabad.org) was commented somewhere in Midrash Rabba and construed as an injunction to light candles during Sabbat...
I found this info in Gérard Haddad's Les sources talmudiques de la psychanalyse (Talmudic sources of psychoanalysis), but unfortunately I didn't write down excerpt where this affirmation pops up and therefore cannot render it exactly how it was phrased...
Can somebody confirm me this interpretation (with a quote from Midrash, preferably in English...) ?
In advance, thanks a lot ! Regards, Seb
