YOu have provided no evidence for a period before 1250BC either. Its because you cannot.
Israelites - Wikipedia, the free encyclopedia
The name Israel first appears c. 1209 BCE, at the end of the Late Bronze Age and the very beginning of the period archaeologists and historians call Iron Age I, in
an inscription of the Egyptian pharaoh
Merneptah. The inscription is very brief and says simply: "Israel is laid waste and his seed is not". The hieroglyph accompanying the name "Israel" indicates that it refers to a people, most probably located in the highlands of Samaria.
[15]
Over the next two hundred years (the period of Iron Age I) the number of highland villages increased from 25 to over 300
[16] and the settled population doubled to 40,000.
[17] There is general agreement that the majority of the population living in these villages was of Canaanite origin.
[16] By the 10th century BCE a rudimentary state had emerged in the north-central highlands,
[18] and in the 9th century this became a kingdom. The kingdom was sometimes called Israel by its neighbours.
