Cuneiform law
Cuneiform law is generally classified separately from later Middle Eastern law, but has been viewed as a predecessor of Biblical and Jewish law. The communities of the Middle East that made use of cuneiform law were generally all in contact with one another, and developed similar cultures. Akkadian, a cuneiform language, was used throughout the entire area, and even as far as Egypt, for diplomatic communications during the Amarna Period.
Cuneiform
From about 2900 BC, many pictographs began to lose their original function, and a given sign could have various meanings depending on context. The sign inventory was reduced from some 1,500 signs to some 600 signs, and writing became increasingly phonological. Determinative signs were re-introduced to avoid ambiguity. Cuneiform writing proper thus arises from the more primitive system of pictographs at about that time (Early Bronze Age II).
