Ruins of a palace and storeroom from the 10th century were found years ago in the Shephelah. Called Elah Fortress in Khirbet Qeiyafa some identify it with either ancient Shaarayim or Neta'im. It seems Isreal will try selling this archeological site as a possible King David's palace.

Besides the buildings, archeologists discovered what is now the earliest sample of Hebrew written written in a Proto-Canaanite script. It is possibly the fragment of a letter. Discovered some years ago, the text was deciphered recently.

English translation of the deciphered text echoes much of the Old Testament.
1' you shall not do [it], but worship the [Lord].
2' Judge the sla[ve] and the wid[ow] / Judge the orph[an]
3' [and] the stranger. [Pl]ead for the infant / plead for the po[or and]
4' the widow. Rehabilitate [the poor] at the hands of the king.
5' Protect the po[or and] the slave / [supp]ort the stranger.
Isaiah 1:16-17 (NRSV)
cease to do evil,
learn to do good;
seek justice,
rescue the oppressed,
defend the orphan,
plead for the widow.
