Leviticus 19:13-15

13You must not rob another person. You must not keep a slave's money until the morning.

14You must not speak bad words against a person who is deaf. You must not put something in front of a blind person, to make them fall down. I am the Lord. Obey me.

15You must be fair to other people when you judge them. You must not be more kind to a rich person than to a poor person. You must be fair to everyone.
