Book of Ezekiel 2,8-10.3,1-4.
The Lord GOD said to me: As for you, son of man, obey me when I speak to you: be not rebellious like this house of rebellion, but open your mouth and eat what I shall give you. It was then I saw a hand stretched out to me, in which was a written scroll which he unrolled before me. It was covered with writing front and back, and written on it was: Lamentation and wailing and woe! He said to me: Son of man, eat what is before you; eat this scroll, then go, speak to the house of Israel. So I opened my mouth and he gave me the scroll to eat. Son of man, he then said to me, feed your belly and fill your stomach with this scroll I am giving you. I ate it, and it was as sweet as honey in my mouth. He said: Son of man, go now to the house of Israel, and speak my words to them.
