What is the meaning of "Chayim Atzemo"?
Rashi: Their life increases in Shalom and good.
Malbim: Their hatred intensified to the point of [desire to take my] life.
What increased?
Rashi: My haters, due to false words.
Radak: The children and property of my haters.
Malbim: My haters' hatred.
What are "Son'ei Sheker"?
Radak: They hate me for no reason. This is like "Ach la'Sheker Shamarti" (Shmuel I, 25:21).
Is this connected to the previous verse?
Radak: Yes. My enemies have good and wealth, and I am always pained, poor and crushed.
Malbim: Yes. One who is hated for a reason, he can remove the reason and the hatred will cease. If a Rasha hates a Tzadik for pursuing good, if he covers up his good deeds, the hatred will cease. I publicize my sin, and even so my enemies hate me - I pursue good, so they do not believe [that I sinned]!
