Jeremias 36:4

4 So Jeremiah called Baruch son of Neriah, and while Jeremiah dictated all the words the Lord had spoken to him, Baruch wrote them on the scroll.

4 Then Jeremiah sent for Baruch, the son of Neriah; and Baruch took down from the mouth of Jeremiah all the words of the Lord which he had said to him, writing them in a book.
