This law of the Torah, which is about a person’s struggle with his internal evil, is echoed in the spirit of the book of Psalms.
“You shall not accept a false report; do not place your hand with a wicked person” means that you should not support the ego that lives inside you and is your nature. Thus I distinguish between my real self and my evil, egoistic self.
My real self is based on their oppositeness, on the feeling of the Creator, which I begin to identify with the Creator, while my egoistic self constantly grows. The difference between them grows accordingly: I can determine my negative attributes towards the spiritual object (the Creator) more clearly, and thus my request becomes stronger and more refined.
“To be a false witness” means not to bow to my ego’s opinion, since when it grows it presents such logical arguments to a person that it is simply impossible to refute them by our simple mind.
In such a case the connection between people becomes very meaningful, the connection between a person and the right environment, since otherwise he draws away from the spiritual work.
