According to the Hebrew Bible, Nahshon was a son of Amminadab, descendant in the fifth generation of Judah, and brother-in-law of Aaron.
He was an Israelite and a Judahite, and a member of the Perezite and Hezronite clans, through his descent from Jacob, Judah, Perez, and Hezron, respectively.
[6] By the same account, those of the Israelites who were among the original number that had set out from Egypt, of whom Nahshon was one, did not survive the forty-year sojourn in the wilderness to enter the Promised Land of Canaan.
[11] Owing to his direct descent from Judah and to his being the progenitor of so many kings, Nahshon is extolled by the rabbis as a most noble man.
Nahshon's sister Elisheba married Aaron,[12] and this is especially mentioned as a hint that one should take care to select a wife whose brothers are noble.
This letter, the numerical value of which is six, indicates that Nahshon was the ancestor of six men — David, the Messiah, Daniel, Hananiah, Mishael, and Azariah — each of whom was distinguished for six praiseworthy qualities.
