Leviticus 18:17

18:17 You must not have sexual intercourse with both a woman and her daughter; you must not take as wife either her son’s daughter or her daughter’s daughter to have intercourse with them. They are closely related to her – it is lewdness.

Deuteronomy 27:23

27:23 ‘Cursed is the one who has sexual relations with his mother-in-law.’ Then all the people will say, ‘Amen!’

Amos 2:7

2:7 They trample on the dirt-covered heads of the poor;

they push the destitute away.

A man and his father go to the same girl;

in this way they show disrespect for my moral purity.
