Numbers 5:18-19

5:18 Then the priest will have the woman stand before the Lord, uncover the woman’s head, and put the grain offering for remembering in her hands, which is the grain offering of suspicion. The priest will hold in his hand the bitter water that brings a curse. 5:19 Then the priest will put the woman under oath and say to the her, “If no other 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.

Numbers 5:23-24

5:23 “‘Then the priest will write these curses on a scroll and then scrape them off into the bitter water. 5:24 He will make the woman drink the bitter water that brings a curse, and the water that brings a curse will enter her to produce bitterness.

Numbers 5:27

5:27 When he has made her drink the water, then, if she has defiled herself and behaved unfaithfully toward her husband, the water that brings a curse will enter her to produce bitterness – her abdomen will swell, her thigh will fall away, and the woman will become a curse among her people.

tn The expression has been challenged. The first part, “bitter water,” has been thought to mean “water of contention” (so NEB), but this is not convincing. It has some support in the versions which read “contention” and “testing,” no doubt trying to fit the passage better. N. H. Snaith (Leviticus and Numbers [NCB], 129) suggests from an Arabic word that it was designed to cause an abortion – but that would raise an entirely different question, one of who the father of a child was. And that has not been introduced here. The water was “bitter” in view of the consequences it held for her if she was proven to be guilty. That is then enforced by the wordplay with the last word, the Piel participle הַמְאָרֲרִים (hamararim). The bitter water, if it convicted her, would pronounce a curse on her. So she was literally holding her life in her hands.

sn This ancient ritual seems to have functioned like a lie detector test, with all the stress and tension involved. It can be compared to water tests in the pagan world, with the exception that in Israel it was stacked more toward an innocent verdict. It seems to have been a temporary provision, for this is the only place that it appears, and no provision is made for its use later. It may have served as a didactic force, warning more than actually legislating. No provision is made in it for a similar charge to be brought against the man, but in the case of the suspicion of the woman the man would be very hesitant to demand this test given the harshness on false witnessing in Israel. The passage remains a rather strange section of the Law.

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

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.

sn The words written on the scroll were written with a combination of ingredients mixed into an ink. The idea is probably that they would have been washed or flaked off into the water, so that she drank the words of the curse – it became a part of her being.
