Hebrews 9:13-14
For if the blood of goats and bulls, and a [burnt] heifer's ashes sprinkled on people who had been [ceremonially] defiled, could purify them so as to make them [ceremonially] clean on the outside,
Hebrews 12:24
and to Jesus, the Mediator of a New Agreement [between God and mankind], and to the sprinkled blood [of Jesus], which says better things [to us] than [the blood of] Abel did. [Note: The contrast seems to be that "Abel's blood called for vengeance and death (See Gen. 4:10) whereas the blood of Christ provides mercy and life"].
1 Peter 1:2
These people have been [specially] selected, and [their acceptance was] pre-planned by God the Father, and they were set apart through [the work of] the Holy Spirit. This resulted in their obedience and sprinkling [Note: This is a figurative reference to the Old Testament practice of cleansing, See Exodus 24:7-8] by the blood of Jesus Christ. May God's unearned favor and peace be continually upon you.
