Numbers 35:16

35:16 “But if he hits someone with an iron tool so that he dies, ³  he is a murderer. The murderer must surely be put to death.

Numbers 35:31

35:31 Moreover, you must not accept a ransom for the life of a murderer who is guilty of death; he must surely be put to death.

[3:10]  ¹ tc The LXX includes the following words here: “and all things pertaining to the altar and within the veil.” Cf. Num 18:7.

[3:10]  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.

[35:16]  ³ tn the verb is the preterite of “die.” The sentence has :“if…he strikes him and he dies.” The vav (ו) consecutive is showing the natural result of the blow.
