Leviticus 19:11-14 - Dealing Honestly
11 Ye shall not steal, and ye shall not deal falsely, and ye shall not lie one to another. 12 And ye shall not swear by my name falsely, and profane the name of thy God: I am Jehovah.
13 Thou shalt not oppress thy neighbour, neither rob him. The wages of the hired servant shall not abide with thee all night until the morning. 14 Thou shalt not revile a deaf person, and thou shalt not put a stumbling-block before a blind one; but thou shalt fear thy God: I am Jehovah.
