"51Suppose ye that I am come to give peace on earth? I tell you, Nay; but rather division: 52For from henceforth there shall be five in one house divided, three against two, and two against three. 53The father shall be divided against the son, and the son against the father; the mother against the daughter, and the daughter against the mother; the mother in law against her daughter in law, and the daughter in law against her mother in law."
