Deuteronomy 27:22

Cursed is he that lies with his sister by his father or his mother: and all the people shall say, So be it.

Cursed be he that lieth with his sister, the daughter of his father, or the daughter of his mother. And all the people shall say, Amen.

‘Cursed is he who lies with his sister, his father’s daughter or his mother’s daughter.’ All the people shall say, ‘Amen.’
