'Clans' in the Bible

Then the clans of Judah will say in their hearts, ‘A strong support for us are the inhabitants of Jerusalem through the Lord of hosts, their God.’

“In that day I will make the clans of Judah like a firepot among pieces of wood and a flaming torch among sheaves, so they will consume on the right hand and on the left all the surrounding peoples, while the inhabitants of Jerusalem again dwell on their own sites in Jerusalem.
