Albert Barnes Commentary Ezekiel 2:9

"And when I looked, behold, a hand was put forth unto me; and, lo, a roll of a book was therein;" — Ezekiel 2:9 (ASV)

Was sent – Rather, was put forth.

A roll of a book – The book was one of the ancient kind, written on skins rolled up together. Hence, the English term 'volume' (Psalms 40:7). The writing was usually on one side, but in this case, it was written within and without—on both sides—the writing, as it were, running over to express the abundance of the calamities in store for the devoted people.

To eat the book signifies to be thoroughly filled with its contents (Jeremiah 15:16). There should be no break between Ezekiel 2:10 and Ezekiel 3:0.
