Deuteronomy 18:6-18:13

If a Levite would go, from any of the settlements throughout Israel where he has been residing, to the place that the Lord has chosen, he may do so whenever he pleases. He may serve in the name of the Lord his God like all his fellow Levites who are there in attendance before the Lord. They shall receive equal shares of the dues, without regard to personal gifts or patrimonies. When you enter the land that the Lord your God is giving you, you shall not learn to imitate the abhorrent practices of those nations. Let no one be found among you who consigns his son or daughter to the fire, or who is an augur, a soothsayer, a diviner, a sorcerer, one who casts spells, or one who consults ghosts or familiar spirits, or one who inquires of the dead. For anyone who does such things is abhorrent to the Lord, and it is because of these abhorrent things that the Lord your God is dispossessing them before you. You must be wholehearted with the Lord your God.
