How did the rooster become france's national symbol? by Gerard Briais,
The choice of the rooster as an emblem refers to a roman joke on Gauls playing on the Latin word "Gallus" which is he same for rooster and Gaulish. Although often used as a symbol of France, especially by sports federations, it has never been chosen as the official symbol even if you can find one on the garden gate of Elysees palace:
The symbolism of the rooster is related to the usual behavior of roosters, their panache, and their character. The Gallic rooster is with Marianne, one of the allegorical symbols and one of the emblems of France. The fighting rooster (coq hardi) is also the symbol of the Walloon Movement, the French Community of Belgium and the Walloon Region.
Christian symbol (in the Bible, the rooster is considered the most intelligent animal Job 38,36) it overcomes many church steeples and, because of his valor, many monuments erected to the dead citizens for France during the wars.
The Tribe of Reuben begins the Process of Repentance.
See Genesis 37:29. This is based on a Midrash (Breishit Rabah 84;19)..
Another Midrash however says that the first to return will be from Gilead of Manasseh.
