Deuteronomy 12:22

Even as the roebuck and the hart is eaten, so thou shalt eat them: the unclean and the clean shall eat of them alike.

Cross-reference

Deuteronomy 12:15 is the original statement that unclean may eat meat like gazelle; this verse repeats that permission.

Deuteronomy 12:16 adds the prohibition against eating blood, complementing the permission to eat meat here.

Deuteronomy 15:22 uses the same phrase 'as the gazelle and the deer' to permit unclean and clean eating.
