Numbers 18:5

Of the sanctuary, i.e. of the holy, and of the most holy, place. Upon the children of Israel, for coming too near the holy place, or for usurping any part of your sacred function, or for any other miscarriage which they may be guilty of through your carelessness or remissness, in which case they shall perish for their error, but their blood will I require at your hands, who should have advised them better, or overruled them.
