Sefer Ha’mitzvos Ha’Katzar (The concise book of mitzvos) By the Chofetz Chaim
This book lists the Torah mitzvos that can be observed today
Second Section – the Negative Commandments
66. It is a negative commandment “do not have compassion for a poor person when judging a court case”
As it states in Shemos (Exodus) 23:3, “and do not favor the poor man in his argument,” and as it states in Vayikra (Leviticus) 19:15, “do not turn towards the poor man.” The judge should not say: he is a poor man and we are obligated to support him. Therefore, I will side with him in this case, so he can be supported with dignity.
This applies in all places and at all times.
4. Be kind to yourself. Speaking badly even about yourself is unethical.
