In 1960, the Israeli archaeologist Joseph Naveh excavating at a small Judahite fortress on the Mediterranean coast — Mesad Hashavyahu, in the Yavne-Yam region a few miles south of modern Tel Aviv — recovered a complete pottery ostracon from the gateway guardroom. Fourteen lines of Hebrew cursive were preserved on the sherd, written in the closing decades of the seventh century BC, the reign of Josiah. The text is a petition, addressed to the local governor, from a field laborer named in some readings as Hoshayahu son of Shobai. He had been harvesting in the fields outside the fortress; a foreman named Hoshayahu had seized his cloak and refused to return it. The petition reads, in Naveh's translation: "Let my lord the governor hear the word of his servant. Your servant was harvesting in Hasar-Asam. Your servant harvested and finished and stored before stopping. When your servant had finished my harvest and stored, days ago, Hoshayahu son of Shobai came and took your servant's garment. All my brothers will testify for me, those harvesting with me in the heat of the sun — my brothers will testify for me. Truly I am innocent. Return my garment, and if not, it is for the governor to return your servant's garment, and grant him mercy." The ostracon's appeal rests directly on Exodus 22:26–27 and Deuteronomy 24:12–13, where the Torah requires that a pledged garment be returned to its poor owner before sundown so he may sleep in it. The laborer is not citing chapter and verse — he is invoking the working substance of the law as he expects the governor to know it. The text is the earliest extra-biblical attestation of the Mosaic pledge protection in everyday Judean legal practice, written within a generation of the discovery of the Book of the Law in 622 BC under Josiah. The ostracon is on display at the Israel Museum, Jerusalem.

Dated to the reign of Josiah, this ostracon provides the earliest extra-biblical evidence that Mosaic pledge law — specifically the garment-return provisions of Exodus 22 and Deuteronomy 24 — functioned as operative legal custom in seventh-century BC Judah, demonstrating that Torah statutes shaped everyday administrative practice outside the Jerusalem temple establishment.
