Grimm gests of Jacko and Esaup, fable one

Jacob Grimm, writer of Grimm's Fairy Tales

Aesop's Fables. The following fable of the Ondt and the Gracehoper is based on Aesop's The Ant and the Grasshopper.

Esau: (Hebrew עֵשָׂו, Standard Hebrew ʿEsav, Tiberian Hebrew ʿĒśāw) is the son of Isaac and Rebekah and the older twin brother of Jacob in the biblical Book of Genesis, whom in the Torah, was tricked by Jacob into giving up his birthright (leadership of Israel) for a "mess of pottage" (meal of lentils). (Genesis 25:29-34). From this, "Esau" in western religions has metaphorically stood for anyone who is tricked into a worthless bargain. http://en.wikipedia.org/wiki/Esau

This explains the 'grimm gest' (or trick) of Jacko (Jacob) played on his twin brother Esau.
