Proverbs 26:5

26:5 Answer a fool according to his folly, ¹ 

lest he be wise in his own estimation. ² 

Matthew 22:46

22:46 No one ³  was able to answer him a word, and from that day on no one dared to question him any longer.

Mark 12:34

12:34 When Jesus saw that he had answered thoughtfully, he said to him, “You are not far from the kingdom of God.” Then no one dared any longer to question him.

[26:5]  ¹ sn The apparent contradiction with the last verse has troubled commentators for some time. The Rabbis solved it by saying that v. 4 referred to secular things, but v. 5 referred to sacred or religious controversies. While this does not resolve the issue, it does give a sound application for the two verses together – in negligible issues one should just ignore the stupid person, but in issues that matter the fool must be dealt with, lest credence be given to what he says (W. G. Plaut, Proverbs, 266). The text presents two proverbs each of which presents an aspect of the whole truth. One should not lower himself to the level of the fool, but there are times when the lesser of two evils is to do so, other than let the fool gain confidence that he is a wise person or be considered wise by others. Paul, for example, talked like a “fool” to correct the foolish ideas of the Corinthians (2 Cor 11:16-17; 12:11).
