Matthew Poole and continuators on Proverbs 26:4

4 Answer not a fool according to his folly , lest thou also be like unto him .

How can these contrary rules be reconciled, answer him not, and answer him? Ans. Easily, by considering the difference of Persons, and Times, and Places, and other circumstances, and of the manner of answering. And such seemingly contradictory Precepts are not onely used by, but are esteemed Elegant in, other Authors, Answer him not, when he is incorrigible, or when he is enflamed with Passion or Wine, &c. or when it is not necessary, nor likely to do him good. Answer him, when he is capable of receiving good by it, or when it is necessary for the glory of God, or for the discharge of a Man's duty, or for the good of others.

So as to imitate his folly, by such passionate, or reproachful, or foolish speeches as he useth to thee.

Shew thy self to be as great a fool as he.
