I believe every spouse has at least a hint of jealousy in them. We are made in the image of God and He is a jealous God. Exodus 34:14, “Do not worship any other god, for the Lord, whose name is Jealous, is a jealous God.”
The test is given in Numbers 5:11-30. It is a longer read than I like to give in my posts but it is important to get the entire picture.
Numbers 5:11-30, 11 Then the Lord said to Moses, 12 “Speak to the Israelites and say to them: ‘If a man’s wife goes astray and is unfaithful to him 13 by sleeping with another man, and this is hidden from her husband and her impurity is undetected (since there is no witness against her and she has not been caught in the act), 14 and if feelings of jealousy come over her husband and he suspects his wife and she is impure—or if he is jealous and suspects her even though she is not impure— 15 then he is to take his wife to the priest. He must also take an offering of a tenth of an ephah of barley flour on her behalf. He must not pour oil on it or put incense on it, because it is a grain offering for jealousy, a reminder offering to draw attention to guilt. 16 “‘The priest shall bring her and have her stand before the Lord. 17 Then he shall take some holy water in a clay jar and put some dust from the tabernacle floor into the water. 18 After the priest has had the woman stand before the Lord, he shall loosen her hair and place in her hands the reminder offering, the grain offering for jealousy, while he himself holds the bitter water that brings a curse. 19 Then the priest shall put the woman under oath and say to her, “If no other man has slept with you and you have not gone astray and become impure while married to your husband, may this bitter water that brings a curse not harm you. 20 But if you have gone astray while married to your husband and you have defiled yourself by sleeping with a man other than your husband”— 21 here the priest is to put the woman under this curse of the oath—“may the Lord cause your people to curse and denounce you when he causes your thigh to waste away and your abdomen to swell. 22 May this water that brings a curse enter your body so that your abdomen swells and your thigh wastes away.” “‘Then the woman is to say, “Amen. So be it.”
23 “‘The priest is to write these curses on a scroll and then wash them off into the bitter water. 24 He shall have the woman drink the bitter water that brings a curse, and this water will enter her and cause bitter suffering. 25 The priest is to take from her hands the grain offering for jealousy, wave it before the Lord and bring it to the altar. 26 The priest is then to take a handful of the grain offering as a memorial offering and burn it on the altar; after that, he is to have the woman drink the water. 27 If she has defiled herself and been unfaithful to her husband, then when she is made to drink the water that brings a curse, it will go into her and cause bitter suffering; her abdomen will swell and her thigh waste away, and she will become accursed among her people. 28 If, however, the woman has not defiled herself and is free from impurity, she will be cleared of guilt and will be able to have children.
29 “‘This, then, is the law of jealousy when a woman goes astray and defiles herself while married to her husband, 30 or when feelings of jealousy come over a man because he suspects his wife. The priest is to have her stand before the Lord and is to apply this entire law to her. 31 The husband will be innocent of any wrongdoing, but the woman will bear the consequences of her sin.’”
In Verse 14 the King James calls it a Spirit of Jealousy whether the wife is guilty or innocent. What an awful way to be treated as a bride. Sounds like something we would hear about from the Middle East.
It is important to note that there is NO test for the husband. Why? If we see the true nature of God it is revealed. Our husband is Jesus and he will never be an adulteress to us, the church, His bride. We, as husbands, are to act as Jesus does to us to our own bride. We, as the church and the bride of Christ, are to act accordingly to Jesus. I believe, no, I know, that if we acted as we are taught in Ephesians 5 and love our spouse as in the Song of Solomon our world would be much better. Our children would see the true example of God's love for us.
As far as the test in Numbers 5, let's not give our spouse any reason to have us drink the bitter water from that cup.
Our love for God is tested, but not His love for us!
