Went up against Damascus, and took it. — We learn from the inscriptions that Damascus stood a two years’ siege. (The Eponym-list makes Tiglath Pileser march against Damascus for two successive years, namely 733 and 732 B.C.)
Carried the people of it captive to Kir. — (Comp. Amos 1:5; Amos 9:7.) The name Kir is not found in the fragmentary remains of the annals of Tiglath Pileser. Schrader (p. 261 seq.) gives a mutilated inscription, apparently relating to the fall of Damascus.
And slew Rezin. — Sir H. Rawlinson found this fact recorded on a tablet of Tiglath Pileser’s, since unfortunately lost. In the inscription just referred to Tiglath says: “I entered the gate of his city; his chief officers alive [I took, and] on stakes I caused to lift them up” (i.e., impaled them).
Kir was the aboriginal home of the Arameans, according to Amos 9:7. It is mentioned along with Elam in Isaiah 22:6. “It has been generally identified with the district by the river Cyrus (the modern Georgia). But, besides the linguistic objection pointed out by Delitzsch (Qir cannot be equivalent to Kúr), it appears that the Assyrian empire never extended to the Cyrus. We must, therefore, consider Kir to be a part of Mesopotamia.” (Cheyne.)
