Then will I sprinkle clean water upon you
Not baptismal water, as Jerom; an ordinance indeed of the Gospel, and to which the Jews will submit when converted; and which is performed by water, but not by sprinkling, nor does it cleanse from sin; and is administered by men, and is not an operation of God, as this is: rather the regenerating grace of the Spirit; though this does not purify from all sin, and besides is intended in the next verse: it seems best to understand it of the blood of Christ, the blood of sprinkling, and of justification from sin, and pardon of it by it; so Kimchi and Jarchi interpret of purification by atonement; and the Targum is,
``I will forgive your sins, as one is cleansed by the water of sprinkling, and the ashes of a heifer, which is for a sin offering:''and ye shall be clean from all your filthiness, and from all your idols
will I cleanse you;
the blood of Christ cleanses from all sin; by it men are justified from all things, and are made perfectly pure and spotless in the sight of God; they are cleansed from original sin, the pollution of their nature; from all actual sins and transgressions, which are very defiling; from sins of heart, lip, and life; even from such as are idols, set up in the heart, and served.
