Leviticus 17:16

But if he wash [them] not,.... Neither wash his clothes: nor bathe his flesh; if he is negligent, and does not take care to make use of these ablutions:

then he shall bear his iniquity; his guilt shall remain on him, and he shall suffer the punishment the law exposes him to, either by the hand of God, or the civil magistrate, which is due to persons that enter into the sanctuary in their uncleanness, or eat of holy things. For not washing his body the punishment was cutting off, and for not washing his garments, beating, as Jarchi says.
