'Chiefs' in the Bible

But the eye of their God was on the chiefs of the Jews, and they did not make them give up working till the question had been put before Darius and an answer had come by letter about it.

So I put on one side twelve of the chiefs of the priests, Sherebiah, Hashabiah, and ten of their brothers with them,

Take care of them and keep them, till you put them on the scales before the chiefs of the priests and the Levites and the chiefs of the families of Israel, in Jerusalem, in the rooms of the house of the Lord.

Then Ezra got up, and made the chiefs of the priests and the Levites and all Israel take an oath that they would do this. So they took an oath.
