Proverbs 26:2, 4-5
Proverbs 26:2 ASV
As the sparrow in her wandering, as the swallow in her flying, So the curse that is causeless alighteth not.
Proverbs 26:4-5 ASV
Answer not a fool according to his folly, Lest thou also be like unto him. Answer a fool according to his folly, Lest he be wise in his own conceit.
