Kir

a wall or fortress, a place to which Tiglath-pileser carried the
Syrians captive after he had taken the city of Damascus (2 Kings
16:9; Amos 1:5; 9:7). Isaiah (22:6), who also was contemporary
with these events, mentions it along with Elam. Some have
supposed that Kir is a variant of Cush (Susiana), on the south
of Elam.
