Who WEREN'T the Habiru
by Jerry Rundstrom
It is inconceivable that a vassal of the Pharaoh could have written to the Pharaoh at the exact time that Israel was invading Canaan, complaining about the incursions of the Habiru, but not about the trouble being caused by the Hebrews.
The only thing that does make sense is that, while not ALL Habiru had to be Hebrews, some of the Hebrews had been branded with the derogatory 'Habiru' which the sedentary tribes who were being invaded, could have called a deadly invader.
So, the Habiru weren't an anomaly that just happened to be spreading havoc in Canaan at the same time as the Hebrews were destroying cities.
In the time of the 14th century BC, and in the context of Canaan, the Habiru had to have been Israel.
