I have not eaten thereof in my mourning - in a season of sorrow, which brought defilement on sacred things; under a pretense of poverty, and grudging to give any away to the poor.
neither ... for any unclean use - that is, any common purpose, different from what God had appointed and which would have been a desecration of it.
nor given ought thereof for the dead - on any funeral service, or, to an idol, which is a dead thing.
