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.
Kir of Moab
Isaiah 15:1. The two strongholds of Moab were Ar and Kir, which latter is probably the Kir-haraseth (16:7) following.
