Thematic Bible: Notaries in courts of justice

So I took the document of the purchase, that which was sealed according to the law and custom, and the open copy. And I gave the document of the purchase to Baruch the son of Neriah, the son of Maaseiah, before the eyes of Hanameel my uncle's son, and before the eyes of the witnesses who wrote in the purchase document, before all the Jews who sat in the court of the guard.
