'Tithes' in the Bible

See, I have given the Levites all the tithes in Israel for an inheritance, for their service which they perform -- the service of the tent of meeting.

But I have given to the Levites for an inheritance the tithes of the Israelites that are offered to the Lord as a raised offering. That is why I said to them that among the Israelites they are to have no inheritance."

Thus you are to offer up a raised offering to the Lord of all your tithes which you receive from the Israelites; and you must give the Lord's raised offering from it to Aaron the priest.
