<p>9:19 <i>For when every commandment had been spoken by Moses to all the people according to the law, he took the blood of the calves and the goats, with water and scarlet wool and hyssop, and sprinkled both the book itself and all the people</i>- This brings out the link between blood and law-giving; the people were sprinkled with blood as they heard the Law read to them. The new covenant in Christ&rsquo;s blood results in the laws of God being written on our hearts, in our consciences (Heb. 8:10). Then Heb. 10:14-16 goes on to say the placing of the laws on our hearts in this way is in fact a &ldquo;witness&quot; to how His blood sanctifies us. We can&rsquo;t be passive to His sacrifice; the conscience elicited by it, the writing on our hearts, is what propels us forward to live a sanctified life. The language of blood, water, scarlet and hyssop is full of reference to the circumstances surrounding the Lord's death on the cross. It was to this that the Mosaic dedication and cleansing rituals pointed forward, and it only had power on that basis.</p>
