'Sprinkling' in the Bible

For if the blood of goats and bulls, and the ashes of a heifer sprinkling them that have been defiled, sanctify unto the cleanness of the flesh:

By faith he kept the passover, and the sprinkling of the blood, that the destroyer of the firstborn should not touch them.

and to Jesus the mediator of a new covenant, and to the blood of sprinkling that speaketh better than that of Abel.

according to the foreknowledge of God the Father, in sanctification of the Spirit, unto obedience and sprinkling of the blood of Jesus Christ: Grace to you and peace be multiplied.
