'Chiefs' in the Bible

Then the clans of Judah will say in their hearts, ‘The inhabitants of Jerusalem are our strength in the Lord of hosts, their God.’

“In that day I will make the clans of Judah like a firepot in a woodpile, and like a flaming torch among sheaves [of grain]. They will devour all the surrounding peoples on the right hand and on the left; and the people of Jerusalem will again live [securely] in their own place, in Jerusalem.
