Numbers 16:40

16:40 It was a memorial for the Israelites, that no outsider who is not a descendant of ¹  Aaron should approach to burn incense before the Lord, that he might not become like Korah and his company – just as the Lord had spoken by the authority ²  of Moses.

Numbers 18:19

18:19 All the raised offerings of the holy things that the Israelites offer to the Lord, I have given to you, and to your sons and daughters with you, as a perpetual ordinance. It is a covenant of salt ³  forever before the Lord for you and for your descendants with you.”

[16:40]  ¹ tn Heb “from the seed of.”

[16:40]  ² tn Heb “hand.”

[18:19]  ³ sn Salt was used in all the offerings; its importance as a preservative made it a natural symbol for the covenant which was established by sacrifice. Even general agreements were attested by sacrifice, and the phrase “covenant of salt” speaks of such agreements as binding and irrevocable. Note the expression in Ezra 4:14, “we have been salted with the salt of the palace.” See further J. F. Ross, IDB 4:167.
