A person shall not take for himself the trait of humbleness and lowness to the point that he will be low and disgraced. As then he will not serve Hashem Yisborach, as he will think that he is depleted and lost. To this it says “Harcheik Mishochein roh, v’al tischaber loroshoh” – Distance yourself from a bad neighbor; do not associate with a wicked person (Avos 1:7), which intends to say, that a person is also forbidden to consider himself a Roshoh.
