Musar על סוטה 83:5

Now we must explain to you in four chapters four classes of people that do not receive the Divine Presence (Sotah 42a). A company of scoffers, as it is written, "He stretcheth out his hand with scorners" (Hos. 7:8). A company of liars, as it is written, "He that speaketh falsehood shall not be established before mine eyes" (Ps. 101:7). A company of flatterers, as it is written, "That a hypocrite cannot come before Him" (Job 13:16). A company of gossipers, as it is written, "For Thou are not a God that hath pleasure in wickedness; Evil shall not sojourn with Thee" (Ps. 5:5). And now it is important to acquaint you with their ways and to divide the matter into proper divisions, for there is great advantage in understanding this matter thoroughly.
