And they shall not sell of it,.... Any part of it that is allotted to them, neither the priests nor the Levites; simony is not to be practised:
neither exchange; for any other land in lieu of it:
nor alienate the first fruits of the land; or appropriate them to any other use than that of the priests and Levites: whatever is appointed for ecclesiastic uses ought not to be converted to any other; nor should church privileges be parted with on any account: ministers and other officers, nay, even private Christians, should not part with their Christian liberty, nor with any of the doctrines and ordinances of the Gospel:
for it is holy unto the Lord; what is separated and devoted to religious uses is sacred to the Lord.
