'Nobles' in the Bible

Then the king ordered Ashpenaz, the chief of his officials, to bring in some of the sons of Israel, including some of the royal family and of the nobles,

At that time my reason returned to me. And my majesty and splendor were restored to me for the glory of my kingdom, and my counselors and my nobles began seeking me out; so I was reestablished in my sovereignty, and surpassing greatness was added to me.

A stone was brought and laid over the mouth of the den; and the king sealed it with his own signet ring and with the signet rings of his nobles, so that nothing would be changed in regard to Daniel.
