Jamieson, Fausset and Brown on Matthew 12:47

47. Then one said unto him, Behold, thy mother and thy brethren stand without, desiring to speak with thee, &c.--Absorbed in the awful warnings He was pouring forth, He felt this to be an unseasonable interruption, fitted to dissipate the impression made upon the large audience--such an interruption as duty to the nearest relatives did not require Him to give way to. But instead of a direct rebuke, He seizes on the incident to convey a sublime lesson, expressed in a style of inimitable condescension.
