Numbers 5:19

5:19 Then the priest will put the woman under oath and say to the her, “If no other ¹  man has had sexual relations with you, and if you have not gone astray and become defiled while under your husband’s authority, may you be free from this bitter water that brings a curse. ² 

Numbers 16:3

16:3 And they assembled against Moses and Aaron, saying to them, “You take too much upon yourselves, ³  seeing that the whole community is holy, every one of them, and the Lord is among them. Why then do you exalt yourselves above the community of the Lord?”

[5:19]  ¹ tn The word “other” is implied, since the woman would not be guilty of having sexual relations with her own husband.

[5:19]  ² sn Although there would be stress involved, a woman who was innocent would have nothing to hide, and would be confident. The wording of the priest’s oath is actually designed to enable the potion to keep her from harm and not produce the physical effects it was designed to do.

[16:3]  ³ tn The meaning of רַב־לָכֶם (rab-lakhem) is something like “you have assumed far too much authority.” It simply means “much to you,” perhaps “you have gone to far,” or “you are overreaching yourselves” (M. Noth, Numbers [OTL], 123). He is objecting to the exclusiveness of the system that Moses has been introducing.
