Jeremiah 51:60

So Jeremiah wrote in a book all the evil that should come upon Babylon ,.... The evil of punishment predicted and threatened: this he delivered, not by word of mouth to Seraiah to relate when he came to Babylon; but he wrote it in a book for him reread; and he wrote it himself; Baruch, his amanuensis, not being now with him:

even all these words that are written against Babylon ; in this and the preceding chapter: this book written by Jeremiah was a copy of them.
