Numbers 18:32

And you will bear no sin concerning it when you offer up the best of it. And you must not profane the holy things of the Israelites, or else you will die.’” ¹

¹ tn The final clause could also be rendered “in order that you do not die.” The larger section can also be interpreted differently; rather than take it as a warning, it could be taken as an assurance that when they do all of this they will not be profaning it and so will not die (R. K. Harrison, Numbers [WEC], 253).
