Some historians who identified Jews with Yadavas suggested that Yadavas migrated out from India after being displaced by a gigantic flood that destroyed their city of Dwarka. This flood is described in Indian scriptures. This drought is now universally recognized by geologists. However, I have seen people being named as Jaiganesh. Jai means “hail.” They have done a lot of cutting the names right in the middle. For example, we can see that the long name of Saraswati is cut right in the middle and only Sarai portion of it is retained. In Hindu legends, Iswar is the son of Brahma; he is even called Brahmaputra, meaning son of Brahma. And in Jewish legends, Issac is the son of Abraham. Rebeccah, the wife of Issac, is none other than Ambica, the wife of Siva of the Hindus. This is nothing but the tributary of river Saraswati, the river by name Ghaggar in India! Ghaggar/Hagar – the resemblance is overwhelming. And the relations they have with Sarai/Saraswati are quite revealing in themselves. At the ripe old age of 137 years, Abraham is said to have married another woman, termed as concubine, named Ketura. And he is said to have fathered six sons through her. Ketura is none other than Hindu goddess Gayatri, considered to be the mother of Vedas.
In his absence, Jacob wins the booty through guile/wisdom. On his comeback, Esau feels extremely cheated. In both cases it is about the title and legacy. Considered to be an extremely important post, both the brothers fight for the post. In order to break the deadlock, it is declared that whoever goes around the world and comes back first would be made the lord of the ganas. Skanda immediately starts on his peacock and goes around the world at a fast pace and comes back in seven days. To his surprise, however, his brother Ganesh is happily seated munching sweets on Mount Kailas, is declared as the winner of the contest, and is given the title of Ganapati/Ganesh or the lord of the ganas. How did he get the title? So after Skanda went away, Ganesh promptly bowed down to his parents and ambulated around them seven times. As the famine drew stronger, it was necessary to find water, and people just about migrated to any place where they thought that they could find water. On their way to Kashmir, it looks like they had a disagreement in this regard. Obviously, the strongest of faiths can wither at the onslaughts of such dramatic famines of hundreds of years.
Despite such close connections being shown, the similarity of two or three names does not break much ice; one problem with these similarities is the causative factor. And as long as the argument stays at this deadlock, it does not progress much in capturing public as well as scholarly imagination. So let me show that there is more resemblance than just two names here. This legend has other variations. For example, in another variation, they were fighting for the two grand daughters of Brahma. Whoever wins the contest gets both their hands in marriage. This fits in with the description of Esau, who is said to be an agile and able hunter. Obviously, Jewish forefathers could not write that Esau is the chief of armies of gods, because they wanted to consider Esau as human in their legends. The legend needed to be suitably modified to fit in the new realm. Similarly, in Ishwar, only Ish has been retained and a consonant has been suffixed, to get Isaac. Similarly, in Jaiganesh, only Jaiga has been retained and a consonant has been added to it as suffix to make it Jagob or Jacob.
Later on, it started being applied to all other gods. They listed down the entire Hindu pantheon as the descendants of Abraham! They are just symbolically representing the gods rejected as Abraham and his descendants in their scriptures. These gods named under Abraham are henceforth to be considered as humans and not as divine. And they have been rejected. Ganesh is many a times called Jaiganesh in the north. In fact, people are named as Jaiganesh, and this particular habit of prefixing jai is a peculiar habit of this deity alone. This was how some of the Jewish scriptures were prepared by Jewish elders. So it is likely that some Yadavas were reluctant to completely give up the worship of Siva. It might not be that they wanted to worship Siva alone, but they probably wanted to continue worshipping the Hindu religious trinity of Brahma/Vishnu/Siva and the Vedic Gods; they probably did not want to completely discard the worship of everyone, especially Siva. They wanted to go back to the old Vedic religion where they worshipped all Vedic gods including Siva and mother goddesses. A disagreement arose, and such Yadavas who wanted to go back to the pre-Krishna religion were discarded. This separation probably took place on the banks of river Ghaggar, near some Siva temple.
