e.rev denotes Arabia in geographic and royal lists, and a mixed group among larger populations.

The attested uses divide evenly between Arabia named among lands or their kings and a mixed group present within a larger population. The same singular absolute noun form occurs in both settings, so the supplied verses do not mark the distinction morphologically.

1. Arabia in lists of lands and kings · dominant

   In Ezekiel 30:5, the singular absolute form stands in a sequence of named peoples and lands; the APB renders the list with “all the Arabia.” In Jeremiah 25:20 and Jeremiah 25:24, it occurs with “all the kings,” and the APB renders the clauses “All Arabia” and “All the kings of Arabia.”

2. A mixed group within a larger people · common

   In Exodus 12:38, the singular absolute form occurs with those who went up and their livestock; the APB renders a “numerous mixed multitude.” In Jeremiah 50:37 it is among the people in her midst, while Nehemiah 13:3 describes separation from Israel; the APB respectively renders “mixed peoples” and “mixed group.”

In the Anselm Project Bible: The APB presents the term as “Arabia” in Ezekiel 30:5, Jeremiah 25:20, and Jeremiah 25:24, but as a “mixed multitude,” “mixed peoples,” or “mixed group” in the other cited verses. These renderings show the verse-level presentation rather than a fixed English equivalent.
