Family Feuds (Luke 12:51-53), cf. Matthew 10:21 supra. Family and social strife is a portent of the end in apocalyptic literature (cf. the mission of Elijah, Malachi 4:5 f.). So the Rabbis interpreted Micah 7:6. History, both in the early Church and on the modern mission field, has abundantly illustrated the sad truth of the saying.
Matthew 10:36 was Jesus-' own experience (Mark 3:21). Lk. rightly interprets sword (Matthew 10:34) as division.
