Answer not a fool according to his folly. Do not lower yourself to the fool's level by answering his silly questions or arguing with him as if he were a sensible man. Lest thou also be like unto him; lest you be led to utter folly yourself or to side with him in his opinions and practices.
Our blessed Saviour never responded to foolish and captious questions in the way that the questioner hoped and desired, he put them by or gave an unexpected turn to them which silenced the adversary.
Instances may be seen in Matthew 21:23, etc.; Matthew 22:21, Matthew 22:22; Luke 13:23, etc.; John 21:21, etc.
