Musar zu Ijow 5:19

And this is the language of the Midrash and Sifrei Zuta [adduced by Yalkut, Parshath Tetze]: "The Holy One Blessed be He said: 'From all the troubles that come upon you I can rescue you. But from lashon hara [slander]? Hide yourself and you will not be hurt!' An analogy: A rich man who loved a villager went to visit him. There was a mad dog there who bit everyone. The rich man said to his beloved: 'My son, if you are in debt to anyone, I will pay your debt, and don't hide from him. But if you see a mad dog, hide from him. For if he bites you, I don't know what I can do for you.' Thus says the Holy One Blessed be He (Iyyov 5:19): 'From six troubles shall He rescue you … but from the lash of the tongue — hide!'"
