Yirmeyah 36:16-18

Orthodox Jewish Bible

¹⁶ Now it came to pass, when they had heard kol haDevarim, they were afraid [looking fearfully] one to the other, and said unto Baruch, We will surely tell HaMelech of all these Devarim.

¹⁷ And they asked Baruch, saying, Tell us now, How didst thou write all these Devarim at his peh (mouth [Jeremiah’s dictation])?

¹⁸ Then Baruch answered them, He pronounced all these Devarim unto me with his peh (mouth, dictation) and I wrote them with dyo (ink) in the Sefer.
