kas.di denotes the Chaldeans as a people, and also their land in place names and geographic expressions.

The term most often identifies the Chaldeans as a people, especially as forces acting against Jerusalem or Judah; it also names their land in expressions such as Ur of the Chaldeans, the land of Chaldea, and movement toward or from that region.

1. The Chaldean people and forces · dominant

   In military and political clauses, the noun identifies the group attacking, besieging, pursuing, or ruling in relation to Judah and Jerusalem. In Jeremiah 32:29 the APB renders the clause, "The Chaldeans who are fighting against this city will come and set this city on fire," while 2 Kings 25:5 presents Chaldean forces pursuing the king; Daniel 2:2 places them among groups summoned before the king.

2. The land or region of Chaldea · common

   In geographic expressions, the noun marks the land connected with Ur, Babylon, exile, or travel. Genesis 11:31 locates the departure at "Ur of the Chaldeans," and Ezekiel 11:24 says that the vision brought Ezekiel "to Chaldea, to the exiles."

In the Anselm Project Bible: The APB commonly presents the term as "the Chaldeans" when the clause concerns people or forces, and as "Chaldea" or "the land of Chaldea" in geographic expressions. These renderings confirm the verse-level setting rather than supplying a separate lexical distinction.
