“And answerable to the border of the priests, the Levites will have twenty five thousand in length, and ten thousand in breadth. All the length shall be twenty five thousand, and the breadth ten thousand. And they will not sell in it, nor barter in it, nor will the firstfruits of the land be alienated, for it is holy to Yahweh.”
The portion for the Levites is also upgraded. It is now holy to Yahweh. As the land is being given to the people, so are the priests' and Levites' portions upgraded another stage to be closer in significance to the heavenly sanctuary. All earthly trade is forbidden in the Levites' portion. The mention of the alienating of the firstfruits might suggest that the Levites had actually, under the kings, been selling the firstfruits, which were for them alone, to outsiders for profit. Now their minds are to be on heavenly things alone. They must seek God alone.
