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 took they Jeremiah, and cast him into the dungeon of Malchijah the king's son, that was in the court of the guard: and they let down Jeremiah with cords. And in the dungeon there was no water, but mire; and Jeremiah sank in the mire.
