This is the Torah: when a man dies in a tent, all who come into the tent and all that is in the tent shall be unclean seven days.
Torah Temimah: Sifrei — “All who come into the tent” — this is one who enters partially; “and all that is in the tent” — this is one who enters completely.
English: “All who come into the tent” — this is one who enters partially; “and all that is in the tent” — this is one who enters completely.
Distinction between partial and complete entry.
Both partial entry into a tent containing a corpse and complete presence inside it convey the seven-day impurity.
