11 And the Lord said to Moses, 12 "Give the following instructions to the people of Israel. "Suppose a man's wife goes astray, and she is unfaithful to her husband 13 and has sex with another man, but neither her husband nor anyone else knows about it. She has defiled herself, even though there was no witness and she was not caught in the act. 14 If her husband becomes jealous and is suspicious of his wife and needs to know whether or not she has defiled herself, 15 the husband must bring his wife to the priest. He must also bring an offering of two quarts of barley flour to be presented on her behalf. Do not mix it with olive oil or frankincense, for it is a jealousy offering-an offering to prove whether or not she is guilty.

Commentary on Numbers 5:11-31
(Read Numbers 5:11-31)
This law would make the women of Israel watch against giving cause for suspicion. On the other hand, it would hinder the cruel treatment such suspicions might occasion. It would also hinder the guilty from escaping, and the innocent from coming under just suspicion. When no proof could be brought, the wife was called on to make this solemn appeal to a heart-searching God. No woman, if she were guilty, could say "Amen" to the adjuration, and drink the water after it, unless she disbelieved the truth of God, or defied his justice. The water is called the bitter water, because it caused the curse. Thus sin is called an evil and a bitter thing. Let all that meddle with forbidden pleasures, know that they will be bitterness in the latter end. From the whole learn, 1. Secret sins are known to God, and sometimes are strangely brought to light in this life; and that there is a day coming when God will, by Christ, judge the secrets of men according to the gospel, Romans 2:16. 2 In particular, Whoremongers and adulterers God will surely judge. Though we have not now the waters of jealousy, yet we have God's word, which ought to be as great a terror. Sensual lusts will end in bitterness. 3. God will manifest the innocency of the innocent. The same providence is for good to some, and for hurt to others. And it will answer the purposes which God intends.
