Now the Prophet more fully explains what we have just dwelt upon. He narrates how a volume of a book was offered to him: that is, a book in the form of a roll was offered to him. For the noun which he uses, mglt, megleth, comes from gll, gelel, to roll, as the word volume among the Latins. For they were formerly accustomed to write on rolls, that is, they had not the form of books so compact and well arranged as we now use, but they had volumes, which barbarians call rolls. Ancient documents were written in this way, for there is nothing ancient in the archives of princes which is not written on rolls. Hence the phrase, "In the volume of the book it is written of me," etc. (Psalm 40:8; Hebrews 10:7.) Now the Prophet says, such a volume was offered to me that I might eat it; and he adds, it was offered to me by a hand sent forth, But by this symbol God more clearly shows that the volume was not merely formed in the air, nor was produced anywhere but in heaven. For if the Prophet had only seen a volume presented to him, he might doubt whether it was sent by God or not. But when the hand which offers the volume appears, and is truly sent forth from God, nothing is wanting for full and complete certainty. He adds, after the volume was unrolled, that he saw it written on each side: by which words he understands not that any brief command was given to him, but that a length of much time was imposed. For if he had only spoken concerning the roll, the Jews might have contemptuously rejected him after three or four days, as if he had come to an ends" A roll was indeed offered to thee, but now thou hast spoken three or four times, is not this sufficient?" Hence, as the Prophet might meet with neglect, he says, the roll was written before and behind He now says, for such was his argument, that lamentations only were written there hgh, hegeh, signifies sometimes meditation and speech simply, but here, because it is connected with lamentations, there is no doubt that it is to be taken for a mournful strain. At length the particle hy, hei, is added in the sense of grieving. On the whole then, the Prophet teaches, that the instruction contained in the book was not sweet or pleasant, but full of sorrow, since truly God here showed proofs of his anger, and this cannot be apprehended unless by its causing grief and lamentations. Now, therefore, we understand that the Israelites were more and more exasperated, when the Prophet said, that he came like a herald who denounced war in the name of God, and, at the same time, had no message of peace. As to the rest of the people, we shall see afterwards, in many places, that he was a messenger of God's mercy, but his duty was to rouse up the Jews, that they might feel God their adversary: thus the Prophet was sent with no other object than that of going, as an armed man, into the midst,, and uttering threats in the name of God. I cannot now proceed further, although what follows is connected with this subject.

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, our English volume Psalm 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 possessed with its contents (compare Ezekiel 3:10; Jeremiah 15:16). There should be no break between Ezekiel 2:10 and Ezek. 3.

A hand was sent - Here the hand signifies not only the instrument of conveyance, but an emblem of the Divine power, which the hand of God always signifies.
A roll of a book - מגלת שפר megillath sepher. All ancient books were written so as to be rolled up; hence volumen, a volume, from volvo, I roll.

And when I looked, behold, an hand was sent unto me,.... Not of an angel, but of Christ himself, in a visionary way; for this was not a real hand, but the likeness of one, as in Ezekiel 8:3; and so the Targum here,
"and I saw, and behold, the likeness of a hand stretched out on the side to me.''
This symbol was to show that his prophecy, that he was sent to deliver, was from heaven and came from Christ; and that hand that delivered it to him would protect and defend him:
and, lo a roll of a book was therein; held in it, and held forth by it, to the prophet. Books were frequently written on parchment or vellum, and rolled about a stick, in form of a cylinder; and hence they were called volumes or rolls, Psalm 40:7. This roll was a symbol of the prophecy of this book.

roll--the form in which ancient books were made.

Roll - Their books were not like ours, but written in parchment and in the length of it, and so one piece fastened to another, 'till the whole would contain what was to be written, and then it was wrapped or rolled about a round piece of wood, fashioned for that purpose.
