Imamat 10:6

10:6 Then Moses said to Aaron and to Eleazar and Ithamar his other two sons, “Do not ¹  dishevel the hair of your heads ²  and do not tear your garments, so that you do not die and so that wrath does not come on the whole congregation. Your brothers, all the house of Israel, are to mourn the burning which the Lord has caused, ³ 

Bilangan 16:46

16:46 Then Moses said to Aaron, “Take the censer, put burning coals from the altar in it, place incense on it, and go quickly into the assembly and make atonement for them, for wrath has gone out from the Lord – the plague has begun!”

[10:6]  ¹ tc Smr has “you must not” (לֹא, lo’) rather than the MT’s “do not” (אַל, ’al; cf. the following negative לֹא, lo’, in the MT).

[10:6]  ² tn Heb “do not let free your heads.” Some have taken this to mean, “do not take off your headgear” (cf. NAB, NASB), but it probably also involves leaving one’s hair unkempt as a sign of mourning (see J. Milgrom, Leviticus [AB], 1:608-9; cf. NCV, TEV, CEV, NLT).

[10:6]  ³ tn Heb “shall weep [for] the burning which the Lord has burned”; NIV “may mourn for those the Lord has destroyed by fire.”
