You hear that Robdar? You're not really a Jew according to shit-for-brains Blue Grass. Why? Because he says so.
It's not because I say so but because that genological records were used to establish if someone was a Jew or not:
Ezekiel 13:9 My hand will be against the prophets who see false visions and utter lying divinations. They will not belong to the council of my people or be listed in the records of the house of Israel, nor will they enter the land of Israel.
Nehemiah 7:63 And from among the priests: the descendants of Hobaiah, Hakkoz and Barzillai (a man who had married a daughter of Barzillai the Gileadite and was called by that name). 64 These searched for their family records, but they could not find them and so were excluded from the priesthood as unclean.
Ezra 2:61 And from among the priests:The descendants of Hobaiah, Hakkoz and Barzillai (a man who had married a daughter of Barzillai the Gileadite and was called by that name).62These searched for their family records, but they could not find them and so were excluded from the priesthood as unclean.
2 Chronicles 31: 16 In addition, they distributed to the males three years old or more whose names were in the genealogical records—all who would enter the temple of the LORD to perform the daily duties of their various tasks, according to their responsibilities and their divisions. 17 And they distributed to the priests enrolled by their families in the genealogical records and likewise to the Levites twenty years old or more, according to their responsibilities and their divisions. 18 They included all the little ones, the wives, and the sons and daughters of the whole community listed in these genealogical records. For they were faithful in consecrating themselves.
