'Chieftains' in the Bible

The chieftains of Judah will say in their heart, 'The inhabitants of Jerusalem are my strength in Yahweh of Armies their God.'

In that day I will make the chieftains of Judah like a pan of fire among wood, and like a flaming torch among sheaves; and they will devour all the surrounding peoples, on the right hand and on the left; and Jerusalem will yet again dwell in their own place, even in Jerusalem.
