9:19 For when Moses had spoken every precept to all the people {m} according to the law, he took the blood of calves and of goats, with water, and scarlet wool, and hyssop, and {n} sprinkled both the book, and all the people,
(m) As the Lord had commanded.
(n) He used to sprinkle.
9:19 For when Moses had. For the events alluded to, see Ex 24:1-8.
Spoken every precept to all the people according to the law. Ex 24:3. All that God had proclaimed in the ten commandments and the accompanying precepts (Ex 21:1-23:33) was written in the book of the covenant. This was read to the people, and they promised obedience (Ex 24:7).
And sprinkled both the book, and all the people. Then the book and all the people were sprinkled with blood (Ex 24:8).
9:19 He took the blood of calves - Or heifers. And of goats, with water, and scarlet wool, and hyssop - All these circumstances are not particularly mentioned in that chapter of Exodus, but are supposed to be already known from other passages of Moses. And the book itself - Which contained all he had said. And sprinkled all the people - Who were near him. The blood was mixed with water to prevent its growing too stiff for sprinkling; perhaps also to typify that blood and water, John 19:34. Ex 24:7,8
9:15-22 The solemn transactions between God and man, are sometimes called a covenant, here a testament, which is a willing deed of a person, bestowing legacies on such persons as are described, and it only takes effect upon his death. Thus Christ died, not only to obtain the blessings of salvation for us, but to give power to the disposal of them. All, by sin, were become guilty before God, had forfeited every thing that is good; but God, willing to show the greatness of his mercy, proclaimed a covenant of grace. Nothing could be clean to a sinner, not even his religious duties; except as his guilt was done away by the death of a sacrifice, of value sufficient for that end, and unless he continually depended upon it. May we ascribe all real good works to the same all-procuring cause, and offer our spiritual sacrifices as sprinkled with Christ's blood, and so purified from their defilement.
