Musar su Salmi 34:3

In the guarding of the tongue there are also many holy qualities: 1) being rescued through it from all of the punishments attendant upon this sin [of lashon hara]. 2) being secure through this of what one has gained of the desired end, that he will not henceforward lose it. (For in not guarding his tongue, he is in danger of losing all, G-d forbid, as explained above in Chapters III and VI in the name of the Midrash.) 3) being called "a man," as it is written (Psalms 34:3): "Who is the man who desires life, etc." For lacking this quality, he is only in the class of an "unspeaking animate object." And in Midrash Shocher Tov we find (Isaiah 57:20): "'And the wicked are driven as the sea' — Just as the sea spews all its mire on the shore, so do the wicked spew their mire on their lips." 4) Because he suppresses himself from "prosecuting" and seeks merit with all his strength, so, above, the ministering angels argue his cause, as we find in Midrash Mishlei.
