The cuneiform tablet documenting a slave sale refers to a pym weight, a polished stone weighing about 7.6 grams. Since these stones were in common use in biblical Israel but not in ancient Mesopotamia, Spar, Paley and Stieglitz concluded the text was written in the Levant, and reflected a business transaction regarding moveable property, namely slaves, in the biblical kingdom of Israel.It was discovered "at Tel Mikhmoret on the Mediterranean coast north of Netanya."
It is very unusual to find a cuneiform fragment in Israel. See, for example, here and here. There is, however, a large archive (unprovenanced but apparently genuine) of cuneiform tablets produced by Judeans in Babylonia. See here and links (cf. here).
