'Chiefs' in the Bible

At that time the king of Aram was making war against Israel; and he had a meeting with the chiefs of his army and said, I will be waiting in secret in some named place.

Then Jehoiachin, king of Judah, went out to the king of Babylon, with his mother and his servants and his chiefs and his unsexed servants; and in the eighth year of his rule the king of Babylon took him.

And he took away all the people of Jerusalem and all the chiefs and all the men of war, ten thousand prisoners; and all the expert workmen and the metal-workers; only the poorest sort of the people of the land were not taken away.
