Numbers 18:23-24

EJ2000(i) 23 But the Levites shall do the service of the tabernacle of the testimony, and they shall bear their iniquity by a perpetual statute throughout your ages, and they shall not possess an inheritance among the sons of Israel. 24 For unto the Levites I have given the tithes of the sons of Israel as inheritance, which they shall offer unto the LORD as offerings; therefore, I have said unto them, Among the sons of Israel they shall possess no inheritance.
