Mine ordinance; either this ordinance here treated of concerning abstaining from holy things when they are unclean; or more generally, that great ordinance whereby I have made them the guardians of holy places and things, to keep them from all defilement by themselves or others. Heb. my watch, i.e. the watch or guard which I have commanded them to keep. Lest they bear sin, i.e. incur guilt and punishment. For it, i.e. for the neglect or violation of it. If they profane it, i.e. their charge, or God's ordinance about it.
