'Mother in law' in the Bible

And when Jesus had come to Peter's house, he saw his mother-in-law laid down and in a fever;

For I have come to set a man at variance with his father, and the daughter with her mother, and the daughter-in-law with her mother-in-law;

And the mother-in-law of Simon lay in a fever. And straightway they speak to him about her.

And rising up out of the synagogue, he entered into the house of Simon. But Simon's mother-in-law was suffering under a bad fever; and they asked him for her.

father against son, and son against father; mother against daughter, and daughter against mother; a mother-in-law against her daughter-in-law, and a daughter-in-law against her mother-in-law.
