'Class' in the Bible

Then Nebuzaradan the [chief executioner and] captain of the bodyguard took the rest of the people who remained in the city, along with those who had deserted and surrendered to him, and the rest of the [so-called better class of] people who were left and carried them into exile in Babylon.

Then all the army officers, including Johanan son of Kareah and Jezaniah son of Hoshaiah and all the people of every class, went to the prophet Jeremiah.

So Jeremiah summoned Johanan son of Kareah and all the army officers who were with him and all the people of every class.

I will see to it that all the Judean remnant that was determined to go and live in the land of Egypt will be destroyed. Here in the land of Egypt they will fall in battle or perish from starvation. People of every class will die in war or from starvation. They will become an object of horror and ridicule, an example of those who have been cursed and that people use in pronouncing a curse.
