Deuteronomy 12:22

Even as the roebuck and the hart is eaten
Which were not only clean creatures, as before observed, but were commonly and frequently eaten, there being plenty of them in those parts:

so thou shalt eat them;
their oxen and calves, their sheep and lambs, their goats and their kids:

the unclean and the clean shall eat of them alike;
no difference being to be made on that account, with respect to common food; (See Gill on Deuteronomy 12:15) which all alike might partake of, notwithstanding any ceremonial uncleanness that any might be attended with.
