Jamieson, Fausset and Brown on Matthew 10:36

36. And a man's foes shall be they of his own household--This saying, which is quoted, as is the whole verse, from Mi 7:6, is but an extension of the Psalmist's complaint (Psa 41:9; 55:12-14), which had its most affecting illustration in the treason of Judas against our Lord Himself (Joh 13:18; Mt 26:48-50). Hence would arise the necessity of a choice between Christ and the nearest relations, which would put them to the severest test.
