Rashi on Numbers 17:28/רש"י על במדבר י״ז:כ״ח

1כל הקרב הקרב וגו׳ WHOSOEVER APPROACHETH [UNTO THE DWELLING OF THE LORD SHALL DIE] — The meaning is: “We cannot be cautious enough in this matter: we are all of us allowed to enter into the court of the appointed tent, but one who betakes himself nearer than his fellow and goes into the appointed tent itself will die!

2האם תמנו לגוע means are we perhaps constantly to be freely exposed to the danger of death?
