Deuteronomy 18:1-13
Offerings for Priests and Levites
1 The Levitical priests—indeed, the whole tribe of Levi—are to have no allotment or inheritance with Israel. They shall live on the food offerings presented to the Lord, for that is their inheritance. 2 They shall have no inheritance among their fellow Israelites; the Lord is their inheritance, as he promised them.
3 This is the share due the priests from the people who sacrifice a bull or a sheep: the shoulder, the internal organs and the meat from the head. 4 You are to give them the firstfruits of your grain, new wine and olive oil, and the first wool from the shearing of your sheep, 5 for the Lord your God has chosen them and their descendants out of all your tribes to stand and minister in the Lord’s name always.
6 If a Levite moves from one of your towns anywhere in Israel where he is living, and comes in all earnestness to the place the Lord will choose, 7 he may minister in the name of the Lord his God like all his fellow Levites who serve there in the presence of the Lord. 8 He is to share equally in their benefits, even though he has received money from the sale of family possessions.
9 When you enter the land the Lord your God is giving you, do not learn to imitate the detestable ways of the nations there. 10 Let no one be found among you who sacrifices their son or daughter in the fire, who practices divination or sorcery, interprets omens, engages in witchcraft, 11 or casts spells, or who is a medium or spiritist or who consults the dead. 12 Anyone who does these things is detestable to the Lord; because of these same detestable practices the Lord your God will drive out those nations before you. 13 You must be blameless before the Lord your God.
Since Priests and Levites did not share in the land that was divided in the new nation of Israel, the people were to share due the priests from the people who sacrifice a bull or a sheep: the shoulder, the internal organs and the meat from the head...The people were to give them the firstfruits of their grain, new wine and olive oil, and the first wool from the shearing of your sheep, for the LORD your God has chosen them and their descendants out of all your tribes to stand and minister in the LORD’s name always...If a Levite moves from one of your towns anywhere in Israel where he is living, and comes in all earnestness to the place the LORD will choose, he may minister in the name of the LORD his God like all his fellow Levites who serve there in the presence of the LORD...He is to share equally in their benefits, even though he has received money from the sale of family possessions...
When the people settle in the Promised Land, the land the LORD your God has given them, do not learn to imitate the detestable ways of the different nations around them...If anyone be found among the Israelites who sacrifices their son or daughter in the fire, or who practices divination or sorcery, interprets omens, engages in witchcraft, or casts spells, or who is a medium or spiritists or who consults the dead...Anyone who does these things is detestable to the LORD...You must be blameless before the LORD your God...
