Easton's Bible Dictionary (1897)
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.
Smith's Bible Dictionary (1863)
e. apparently as the country where they had dwelt before migrating to the region north of Palestine.
Hastings' Dictionary of the Bible (1898) & Schaff's Bible Dictionary
KIR (wall, or place surrounded with walls), the city from which the Syrians emigrated when they came to settle in the region north of Palestine, and to which Tiglath-pileser sent the captive Syrians after the conquest of Damascus. 2 Kgs 16:9; Am 1:5; Hos 9:7. About the location of this city scholars disagree, some placing it in Armenia, on the river Kar, others identifying it with Carena, of Carea, in Media.
