'Registration' in the Bible

as well as the priests who were registered genealogically according to their fathers’ households, and the Levites from twenty years old and upward, by their duties and by their divisions.

The genealogical registration included all their little children, their wives, and their sons and daughters, for the whole assembly, because they consecrated themselves faithfully in holiness.

These men searched for their ancestral registration among those recorded in the genealogies, but it was not located; so they were excluded from the priesthood as [ceremonially] unclean.
