[Egyptian texts about the Shasu and the Land of Yahu]
An inscription in a temple of Amon in Soleb, Nubia, from the reign of Amenhotep III (first half of the fourteenth century), lists several beduin (Shasu) territories including 'the Shasu land of Yahu'. The name also occurs in a copy of the same list in the Amara West temple in Nubia from the reign of Rameses II (second half of thirteenth century), and both could go back to an even earlier prototype.
There is broad agreement that the name corresponds to one of the forms of the name of Yahweh, that it refers to a region in which the Shasu in question lived and moved around, and that either the deity could have taken the name of the region or the region could have taken its name from the deity worshipped by the beduin who lived there.
