Numbers 3:10

So you are to appoint Aaron and his sons, and they will be responsible for their priesthood; ¹  but the unauthorized person ²  who comes near must be put to death.”

Nu 1:51; Nu 3:38; Nu 16:35,40; Nu 18:3; Nu 18:7; 1Sa 6:19; 2Sa 6:7; 1Ch 6:32; 2Ch 26:16-21; Eze 44:8; Ac 6:3,4; Ro 12:7; Eph 2:19; 1Ti 4:15,16; Heb 8:4; Heb 10:19-22

¹ tc The LXX includes the following words here: “and all things pertaining to the altar and within the veil.” Cf. Num 18:7.

² tn The word is זָר (zar), usually rendered “stranger, foreigner, pagan.” But in this context it simply refers to anyone who is not a Levite or a priest, an unauthorized person or intruder in the tabernacle. That person would be put to death.
