The letter (part of the Amarna letters correspondence) reports of the king having smote down the uprising of the Habiru.
[1] The letter begins with an address which is thought typical of the usual beginning of reportage of intelligence.
[2] The mention of the Habiru shows the conflict of the time, as the takeover of city-states or regions by the Habiru.
The map shows various cities and regions, and their respective dealings with the Habiru.
The next closest mention of the Habiru is from the Jerusalem letters of Abdi-Heba, directly south at Jerusalem, letters EA 286, 287, 288, 289, and EA 290.
