'Nobility' in the Bible

The king ordered Ashpenaz, the chief of his court officials, to bring some of the Israelites from the royal family and from the nobility—

I will again bring a conqueroragainst you who live in Mareshah.The nobility of Israel will come to Adullam.

the light of a lampwill never shine in you again;and the voice of a groom and bridewill never be heard in you again.All this will happenbecause your merchantswere the nobility of the earth,because all the nations were deceivedby your sorcery,
