Deuteronomy 12:15-17 New International Version - UK (NIVUK)
15 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. 16 But you must not eat the blood; pour it out on the ground like water. 17 You must not eat in your own towns the tithe of your corn and new wine and olive oil, or the firstborn of your herds and flocks, or whatever you have vowed to give, or your freewill offerings or special gifts.
