Family lists and genealogies are a prominent part of 1 and 2 Chronicles and other Old Testament books. These genealogies were obviously important to Israel, and the Jews kept meticulous records.
Explanation:
Genealogies emphasized the importance of the family unit in Jewish culture. Traditional Jewish culture emphasized marriage between a man and a woman who were responsible for raising children and continuing the legacy of their family with the next generation. The Jews took seriously their responsibility to continue the line that would bring honor to the family name.
