Contradiction with Numbers 18:21
Numbers 18:21 states that tithes are given to the Levites as an inheritance instead of a land possession, which contradicts with the allocation of wagons and oxen to the Levites for carrying the tabernacle as mentioned in Numbers 7:5, where the focus is on sharing physical resources rather than dedicating tithes directly.
Numbers 18:21: And, behold, I have given the children of Levi all the tenth in Israel for an inheritance, for their service which they serve, [even] the service of the tabernacle of the congregation.
