'Mother in law' in the Bible

And [when] Jesus came into Peter's house, he saw his mother-in-law lying down and suffering with a fever.

For I have come to turn a man against his father, and a daughter against her mother, and a daughter-in-law against her mother-in-law.

Now Simon's mother-in-law was lying down, suffering with a fever, and at once they told him about her.

And [after he] set out from the synagogue, he went into Simon's house. And Simon's mother-in-law was afflicted with a high fever, and they asked him on behalf of her.

They will be divided, father against son and son against father, mother against daughter and daughter against mother, mother-in-law against her daughter-in-law and daughter-in-law against mother-in-law."
