'Chiefs' in the Bible

The Lord gave me a vision, and I saw two baskets full of figs put in front of the Temple of the Lord, after Nebuchadrezzar, king of Babylon, had taken prisoner Jeconiah, the son of Jehoiakim, king of Judah, and the chiefs of Judah, and the expert workmen and metal-workers from Jerusalem, and had taken them to Babylon.

And like the bad figs which are so bad that they are of no use for food, so I will give up Zedekiah, king of Judah, and his chiefs and the rest of Jerusalem who are still in this land, and those who are in the land of Egypt:

Give cries of grief, you keepers of sheep; give cries for help, rolling yourselves in the dust, you chiefs of the flock: for the days of your destruction have fully come, and I will send you in all directions, and your fall will be like that of the males of the flock.

There will be no way of flight for the keepers of sheep, no road for the chiefs of the flock to get away safely.

A sound of the cry of the keepers of sheep, and the bitter crying of the chiefs of the flock! for the Lord has made waste their green fields.

And I will make her chiefs and her wise men, her rulers and her captains and her men of war, overcome with wine; their sleep will be an eternal sleep without awaking, says the King; the Lord of armies is his name.
