Deuteronomy 12:15, 20

Nevertheless, you may slaughter your animals in any of your towns and eat as much of the meat as you want, as if it were gazelle or deer, according to the blessing the LORD your God gives you. Both the ceremonially unclean and the clean may eat it.

When the LORD your God has enlarged your territory as he promised you, and you crave meat and say, “I would like some meat,” then you may eat as much of it as you want.
