He that answereth a matter before he heareth [it],.... Who is impatient, and cannot wait to hear it out, but breaks in upon the speaker before he has finished what he has to say; or is rash and precipitate, and returns an answer at once, without weighing and considering, and thoroughly understanding, what is said:
it [is] folly and shame unto him; his answer must be a foolish one, and bring shame and confusion upon him; men should be "swift to hear", and "slow to speak", James 1:9.
