Why does it say "Al Ta'aminu v'Re'a"?
Rashi: It is like the simple meaning. Radak -in this generation, one cannot trust his friend.
Rashi citing Chagigah 16a: Do not sin, and say 'Hashem loves us ? He will pardon us.'
Malbim: There will be such confusion among them to the point that man will divide from his brother. One cannot trust a friend that until now, he trusted in his love.
Who is "Aluf"?
Radak: It is a Gadol, i.e. his older brother.
Malbim: It is the Sar (officer) who teaches him and shows the path to him.
Who is "Shocheves Cheikecha", and why should you guard your mouth's openings from her?
Rashi: It is your Neshamah; it will testify about you. "Pischei Ficha" are the words of your mouth. Radak - this is like "Pesach Devarecha Ya'ir" (Tehilim 119:130).
Radak: Your wife. If you will speak bad about your friend in front of her, she will reveal it.
Malbim: Your wife. Also Shalom Bayis will cease.
