Leviticus 19:11-14 - Dealing Honestly
11 Do not take anyone's property or be false in act or word to another. 12 And do not take an oath in my name falsely, putting shame on the name of your God: I am the Lord.
13 Do not be cruel to your neighbour or take what is his; do not keep back a servant's payment from him all night till the morning. 14 Do not put a curse on those who have no hearing, or put a cause of falling in the way of the blind, but keep the fear of your God before you: I am the Lord.
