Ezekiel 48:14

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.
