Jeremiah 36:18 (KJV)

Now it came to pass, when they had heard all the words, they were afraid both one and other, and said unto Baruch, We will surely tell the king of all these words.

And they asked Baruch, saying, Tell us now, How didst thou write all these words at his mouth?

Then Baruch answered them, He pronounced all these words unto me with his mouth, and I wrote them with ink in the book.

Then said the princes unto Baruch, Go, hide thee, thou and Jeremiah; and let no man know where ye be.

And they went in to the king into the court, but they laid up the roll in the chamber of Elishama the scribe, and told all the words in the ears of the king.
