'Roll' in the Bible

It said, "Write forthwith in a roll an account of what you see, and send it to the seven Churches--to Ephesus, Smyrna, Pergamum, Thyateira, Sardis, Philadelphia and Laodicea."

And the heaven was taken away like the roll of a book when it is rolled up; and all the mountains and islands were moved out of their places.

So I took the roll out of the angel's hand and ate the whole of it; and in my mouth it was as sweet as honey, but when I had eaten it I found it very bitter.
