Sprinkle in the Bible - a Christian perspective
The writer of Hebrews writes that the high priests used to sprinkle the blood of animals on us when we were unclean, but now we have Jesus' blood to consecrate us.
Consecrate - a Christian perspective
In Leviticus, God tells the Hebrew people to consecrate themselves and to be holy. He says that they should do so because God Himself is Holy. Later Jesus would restate this during his sermon on the mount.
