Mark 13:12
Brother will betray brother to death, and a father his child. Children will rebel against their parents and have them put to death — the familial betrayal intensifies the persecution section: the kingdom's division of loyalties (Mark 3:31–35, 10:29–30) will produce literal family betrayals. The intimacy of the betrayal (brother/brother, father/child, children/parents) communicates that the kingdom's claim supersedes every human loyalty — and that those whose loyalties are differently ordered will become persecutors of those who follow Jesus.
