In the volume of the book - במגלת ספר bimgillath sepher, "in the roll of the book." Anciently, books were written on skins and rolled up. Among the Romans these were called volumina, from volvo, I roll; and the Pentateuch, in the Jewish synagogues, is still written in this way. There are two wooden rollers; on one they roll on, on the other they roll off, as they proceed in reading. The book mentioned here must be the Pentateuch, or five books of Moses; for in David's time no other part of Divine revelation had been committed to writing. This whole book speaks about Christ, and his accomplishing the will of God; not only in, The seed of the woman shall bruise the head of the serpent, and, In thy seed shall all the nations of the earth be blessed, but in all the sacrifices and sacrificial rites mentioned in the law. To do thy will - God willed not the sacrifices under the law, but he willed that a human victim of infinite merit should be offered for the redemption of mankind. That there might be such a victim, a body was prepared for the eternal Logos; and in that body he came to do the will of God, that is, to suffer and die for the sins of the world.
