Deuteronomy 12:15-17 Modern English Version (MEV)
15 Notwithstanding, you may kill and eat meat within all your gates, whatever your heart desires, according to the blessing of the Lord your God which He has given you. The unclean and the clean may eat of it, of the gazelle and of the deer, 16 only you must not eat the blood. You shall pour it on the ground like water. 17 You may not eat within your gates the tithe of your grain, your wine, your oil, the firstborn of your herds or of your flock, any of your vows which you vow, your freewill offerings, or the offering of your hand.
