'Letter' in the Bible

Now these are the words of the letter which Jeremiah the prophet sent from Jerusalem to the responsible men among those who had been taken away, and to the priests and the prophets and to all the rest of the people whom Nebuchadnezzar had taken away prisoners from Jerusalem to Babylon;

Shemaiah the Nehelamite sent a letter in his name to Zephaniah, the son of Maaseiah the priest, saying,

And Zephaniah the priest made clear to Jeremiah the prophet what was said in the letter, reading it to him.
