"Think not that I am come to send peace on earth: I came not to send peace, but a sword. For I am come to set a man at variance against his father, and the daughter against her mother, and the daughter in law against her mother in law. And a man's foes shall be they of his own household. He that loveth father or mother more than me is not worthy of me: and he that loveth son or daughter more than me is not worthy of me. And he that taketh not his cross, and followeth after me, is not worthy of me."
Matthew 10:34-38, KJV
"Now the brother shall betray the brother to death, and the father the son; and children shall rise up against their parents, and shall cause them to be put to death. And ye shall be hated of all men for my name's sake: but he that shall endure unto the end, the same shall be saved."
Mark 13:12-13, KJV
"Suppose ye that I am come to give peace on earth? I tell you, Nay; but rather division: For from henceforth there shall be five in one house divided, three against two, and two against three. The 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."
Luke 12:51-53, KJV
