Punishments for Sexual Immorality

10“If a bman commits adultery with the wife of
Hebrew repeats if a man commits adultery with the wife of
his neighbor, both the adulterer and the adulteress shall surely be put to death.

Numbers 5:13-31

13if a man dlies with her sexually, and it is hidden from the eyes of her husband, and she is undetected though she has defiled herself, and there is no witness against her, esince she was not taken in the act, 14and if the spirit of jealousy comes over him and he is jealous of his wife who has defiled herself, or if the spirit of jealousy comes over him and he is jealous of his wife, though she has not defiled herself, 15then the man shall bring his wife to the priest and bring the offering required of her, a tenth of an ephah
An  ephah was about 3/5 bushel or 22 liters
of barley flour. gHe shall pour no oil on it and put no frankincense on it, for it is a grain offering of jealousy, a grain offering of remembrance, hbringing iniquity to remembrance.

16“And the priest shall bring her near and set her before the Lord. 17And the priest shall take holy water in an earthenware vessel and take some of the dust that is on the floor of the tabernacle and put it into the water. 18And the priest shall set the woman before the Lord and iunbind the hair of the woman’s head and place in her hands the grain offering of remembrance, which is the grain offering of jealousy. And in his hand the priest shall have the water of bitterness that brings the curse. 19Then the priest shall make her take an oath, saying, ‘If no man has lain with you, and if you have not turned aside to uncleanness while you were under your husband’s authority, be free from this water of bitterness that brings the curse. 20But if you have gone astray, though you are under your husband’s authority, and if you have defiled yourself, and some man other than your husband has lain with you, 21then’ (let the priest make the woman take the oath of the curse, and say to the woman) j‘the Lord make you a curse and an oath among your people, when the Lord makes your thigh fall away and your body swell. 22May this water that brings the curse kpass into your bowels and make your womb swell and your thigh fall away.’ And the woman shall say, lAmen, Amen.’

23“Then the priest shall write these curses in a book and wash them off into the water of bitterness. 24And he shall make the woman drink the water of bitterness that brings the curse, and the water that brings the curse shall enter into her and cause bitter pain. 25And the priest shall take the grain offering of jealousy out of the woman’s hand mand shall wave the grain offering before the Lord and bring it to the altar. 26And the priest nshall take a handful of the grain offering, as its memorial portion, and burn it on the altar, and afterward shall make the woman drink the water. 27And when he has made her drink the water, then, if she has defiled herself and has broken faith with her husband, the water that brings the curse shall enter into her and cause bitter pain, and her womb shall swell, and her thigh shall fall away, and the woman oshall become a curse among her people. 28But if the woman has not defiled herself and is clean, then she shall be free and shall conceive children.

29This is the law in cases of jealousy, when a wife, pthough under her husband’s authority, goes astray and defiles herself, 30or when the spirit of jealousy comes over a man and he is jealous of his wife. Then he shall set the woman before the Lord, and the priest shall carry out for her all this law. 31The man shall be free from iniquity, but the woman qshall bear her iniquity.”

Deuteronomy 22:22-24

22 rIf a man is found lying with the wife of another man, both of them shall die, the man who lay with the woman, and the woman. sSo you shall purge the evil from Israel.

23If there is a tbetrothed virgin, and a man meets her in the city and lies with her, 24then you shall bring them both out to the gate of that city, and you shall stone them to death with stones, the young woman because she did not cry for help though she was in the city, and the man because he violated his neighbor’s wife. uSo you shall purge the evil from your midst.

Matthew 5:32

32 vBut I say to you that everyone who divorces his wife, except on the ground of sexual immorality, makes her commit adultery, and wwhoever marries a divorced woman commits adultery.

Mark 10:6-12

6But xfrom the beginning of creation, ‘God made them ymale and female.’ 7 zTherefore a man shall leave his father and mother and hold fast to his wife,
Some manuscripts omit  and hold fast to his wife
8and abthe two shall become one flesh.’ So they are no longer two but one flesh. 9 acWhat therefore God has joined together, let not man separate.”

10And in the house the disciples asked him again about this matter. 11And he said to them, adWhoever divorces his wife and marries another commits adultery against her, 12and aeif she divorces her husband and marries another, she commits adultery.”
