Leviticus 7:21

Moreover, the soul that shall touch any unclean [thing],
&c.] Person or thing, the dead body of a man, or the bone of a dead body, or a grave in which it was laid:

as the uncleanness of man;
the issue that runs from a profluvious person:

or [any] unclean beast;
that was so by the law ceremonial; see ( Leviticus 11:4-8 ) :

or any abominable unclean thing;
which the Targum of Jonathan interprets of every unclean reptile: see ( Leviticus 11:20 Leviticus 11:24 Leviticus 11:29 )

and eat of the flesh of the sacrifice of peace offerings, which
[pertain] unto the Lord, even that soul shall be cut off from his
people; (See Gill on Leviticus 7:20).
