'Genealogy' in the Bible

These sought their register [among] those who were reckoned by genealogy, but they were not found: therefore were they deemed polluted and put from the priesthood.

Now these are the heads of their fathers' [houses], and this is the genealogy of those who went up with me from Babylon, in the reign of Artaxerxes the king:

Of the sons of Shecaniah, of the sons of Parosh, Zechariah; and with him were reckoned by genealogy of the males one hundred fifty.
