Luke 1:61

Verse 61. None of thy kindred] As the Jewish tribes and families were kept sacredly distinct, it appears the very names of the ancestors were continued among their descendants, partly through reverence for them, and partly to avoid confusion in the genealogical tables, which, for the sake of distinguishing the inheritances, were carefully preserved in each of the families. It seems to be on this account that the neighbours and relatives objected to a name which had not before existed in any branch of the family.
