Then, to love your neighbor as yourself. you are not to kill, not to commit dultry, not to steal, not to covet (Rom. 13:9). You are not to bear false witness (Matt 19:18; Mark 10:19; Luke 18:20). You must honor all (1 Pet. 2:17). You must not do to another what you would not have done to yourself (Tob. 4:16; Matt 7:12).
