'Officer' in the Bible

And Azariah the son of Nathan was over the officers: and Zabud the son of Nathan was principal officer, and the king's friend:

Geber the son of Uri was in the country of Gilead, in the country of Sihon king of the Amorites, and of Og king of Bashan; and he was the only officer which was in the land.

Then the king of Israel called an officer, and said, Hasten hither Micaiah the son of Imlah.
