Theophylact of Ohrid — as excerpted in the Catena Aurea on Mark 13:9-13

“He also foretells to them a worse evil, that they should suffer persecution from their relations. Wherefore there follows: 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.”
