Malchijah in the Bible

The word which came unto Jeremiah from Jehovah, when king Zedekiah sent unto him Pashhur the son of Malchijah, and Zephaniah the son of Maaseiah, the priest, saying,

And Shephatiah the son of Mattan, and Gedaliah the son of Pashhur, and Jucal the son of Shelemiah, and Pashhur the son of Malchijah, heard the words that Jeremiah spake unto all the people, saying,

Then they took Jeremiah and cast him into the cistern of Malchijah the king’s son, which was in the court of the guardhouse; and they let Jeremiah down with ropes. Now in the cistern there was no water but only mud, and Jeremiah sank into the mud.
