'Chieftains' in the Bible

I will take the blood from their mouthsAnd their detestable things from between their teeth [those repulsive, idolatrous sacrifices eaten with the blood].Then they too will be a remnant for our God,And be like a clan in Judah,And Ekron will be like one of the Jebusites.

And the chieftains of Judah shall say in their heart, The inhabitants of Jerusalem are my strength in Jehovah of hosts their God.

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