'Wickedness' in the Bible

You shall not uncover the nakedness of a woman and her daughter, nor shall you take her son’s daughter or her daughter’s daughter to uncover their nakedness (have intimate relations with them); they are [her] blood relatives; it is an outrageous offense.

‘Do not profane your daughter by making her a prostitute, so that the land will not fall to prostitution and become full of wickedness.

It is immoral and shameful if a man marries a woman and her mother; all three shall be burned in fire, so that there will be no immorality among you.
