Leviticus 19:11-14 - Dealing Honestly
11 Do not steal. Do not deal falsely. Do not lie to one another. 12 Do not swear falsely by my name, so as to profane the name of your God. I am Jehovah.
13 Do not oppress your neighbor and do not rob him. Do not fail to pay your workers at the end of each day. 14 Do not curse a deaf man. Do not place a stumbling block before the blind. You must deeply respect your God. I am Jehovah.
