'Letter' in the Bible

And I saw that {for this very reason, that} on account of apostate Israel committing adultery I divorced her and gave the letter of divorce to her. Yet her treacherous sister Judah was not afraid and she went and prostituted [herself] also.

Now these are the words of the letter that Jeremiah the prophet sent from Jerusalem unto the residue of the elders which were carried away captives, and to the priests, and to the prophets, and to all the people whom Nebuchadnezzar had carried away captive from Jerusalem to Babylon;

The letter was sent by Elasah son of Shaphan and Gemariah son of Hilkiah whom Zedekiah king of Judah had sent to Babylon to Nebuchadnezzar king of Babylon. The letter stated:

that the Lord God of Israel who rules over all has a message for him. Tell him, 'On your own initiative you sent a letter to the priest Zephaniah son of Maaseiah and to all the other priests and to all the people in Jerusalem. In your letter you said to Zephaniah,

now therefore [continued the letter from Shemaiah in Babylon to Zephaniah in Jerusalem], why have you not rebuked Jeremiah of Anathoth, who prophesies to you?

And Zephaniah the priest read this letter in the ears of Jeremiah the prophet.

And I signed on the letter and sealed [it], and I called witnesses as witness, and I weighed out the money on a set of scales.
