Leviticus 19:11-14 - Dealing Honestly
11 Ye shall not steal and ye shall not deceive, and ye shall not lie each to his neighbor. 12 And ye shall not swear in my name for falsehood, and profane the name of thy God: I Jehovah.
13 Thou shalt not oppress thy neighbor, and thou shalt not rob: the wages of the hireling shall not remain with thee till morning. 14 Thou shalt not curse the deaf, and before the blind thou shalt not give a stumbling block, and thou shalt fear thy God: I Jehovah.
