kas.day denotes Chaldeans, appearing both for individuals in courtly groups and for the people identified by their king.

The term most often identifies Chaldeans as a group within royal settings, including speakers before a king, summoned interpreters, accusers, and a class listed with other specialists. It also identifies the people of whom Belshazzar is called king.

1. Chaldeans in royal and specialist settings · dominant

   The singular determined form occurs in addresses to and speech by Chaldeans in Daniel 2:5 and Daniel 2:10; in Daniel 2:10 the APB renders the clause about declaring the king's matter and lists a Chaldean beside a magician and enchanter. Plural forms name Chaldeans who accuse the Jews in Daniel 3:8, who are listed among magicians and soothsayers in Daniel 5:7 and Daniel 5:11, and who are present in Daniel 4:4 although the APB verse does not explicitly render the group.

2. People identified through their king · rare

   In Daniel 5:30, the determined plural form occurs in the identification of Belshazzar as king of the Chaldeans; the APB renders the clause, "Belshazzar, king of the Chaldeans, was killed."

   Daniel 5:30

In the Anselm Project Bible: The APB generally presents the forms as "Chaldeans," both in group listings and in the title "king of the Chaldeans." In Daniel 4:4, however, the supplied translation does not explicitly reflect the term, so its specific English contribution there cannot be isolated from the APB wording.
