"The cowardly king knew these charges were false; but in order to propitiate those who occupied high and influential positions in the nation, he feigned to believe their falsehoods and gave Jeremiah into their hands to do with him as they pleased. Accordingly the prophet was taken and cast “into the dungeon of Malchiah the son of Hammelech, that was in the court of the prison: and they let down Jeremiah with cords.

"Then took they Jeremiah, and cast him into the dungeon of Malchiah the son of Hammelech, that was in the court of the prison: and they let down Jeremiah with cords. And in the dungeon there was no water, but mire: so Jeremiah sunk in the mire."
The EGW passage directly quotes and elaborates on the events described in Jeremiah 38:6, including the details of Jeremiah's imprisonment in the dungeon of Malchiah and his sinking in the mire.

So Zedekiah the king sware secretly unto Jeremiah, saying, As the Lord liveth, that made us this soul, I will not put thee to death, neither will I give thee into the hand of these men that seek thy life.” Then Jeremiah again sounded the Lord's note of warning in the ears of the king.

"Then Zedekiah the king sent, and took Jeremiah the prophet unto him into the third entry that is in the house of the Lord: and the king said unto Jeremiah, I will ask thee a thing; hide nothing from me. Then Jeremiah said unto Zedekiah, If I declare it unto thee, wilt thou not surely put me to death? and if I give thee counsel, wilt thou not hearken unto me? So Zedekiah the king sware secretly unto Jeremiah, saying, As the Lord liveth, that made us this soul, I will not put thee to death, neither will I give thee into the hand of these men that seek thy life."
The EGW passage directly quotes and expands upon the dialogue between Zedekiah and Jeremiah in Jeremiah 38:14-16, including Zedekiah's oath and Jeremiah's warning about the fate of Jerusalem.
