'Clan' in the Bible

In the morning you must present yourselves tribe by tribe. The tribe the Lord selects is to come forward clan by clan. The clan the Lord selects is to come forward family by family. The family the Lord selects is to come forward man by man.

He had the clans of Judah come forward, and the Zerahite clan was selected. He had the Zerahite clan come forward by heads of families, and Zabdi was selected.
