Thematic Bible: Notaries in courts of justice

So I took the deed of purchase, both that which was sealed according to the law and custom, and that which was open: And I gave the deed of purchase unto Baruch the son of Neriah, the son of Mahseiah, in the sight of Hanamel my uncle's son, and in the presence of the witnesses that signed the deed of purchase, before all the Jews that sat in the court of the prison.
