What is "shasu"

Shasu ( from Egyptian š3sw, probably pronounced Shasw) were Semitic-speaking cattle nomads in the Levant from the late Bronze Age to the Early Iron Age or Third Intermediate Period of Egypt. They were organized in clans under a tribal chieftain, and were described as brigands active from the Jezreel Valley to Ashkelon and the Sinai. Some scholars link the Israelites and the Israelite god Yahweh with the Shasu.
