NUM146 And our Sages of blessed memory have said (Arachin 15a; Shochar Tov 39:1): "Our forefathers were tested with ten trials, but their decree was sealed only because of slander, as it is written [this verse]: 'Surely, as you have spoken in my ears, so will I do to you,' and as it is written (Devarim 1:34): 'And Hashem heard the voice of your words and was angry and swore.'" And Torah does not protect slanderers. In the case of Doeg the Edomite, because he spoke slander, his wisdom did not avail him and his Torah did not protect him (Sotah 21a; Sanhedrin 106b).
