Brother will betray brother, and parents and children will turn against each other.
It describes betrayal inside the household itself.
9So be on your guard. You will be delivered over to the councils and beaten in the synagogues. On My account you will stand before governors and kings as witnesses to them. 10And the gospel must first be proclaimed to all the nations. 11But when they arrest you and hand you over, do not worry beforehand what to say. Instead, speak whatever you are given at that time, for it will not be you speaking, but the Holy Spirit. 12Brother will betray brother to death, and a father his child. Children will rise against their parents and have them put to death. 13You will be hated by everyone because of My name, but the one who perseveres to the end will be saved.
