Christ is quoting Micah 7:6: ‘Trust ye not in a friend, put ye not confidence in a guide: keep the doors of thy mouth from her that lieth in thy bosom. 6 For the son dishonoureth the father, the daughter riseth up against her mother, the daughter in law against her mother-in-law; a man's enemies are the men of his own house’ (Micah 7:5-6).
