"Be holy, for I, the Lord your God, am holy." St. Paul put it this way, "Do not be conformed to this age, but be transformed by the renewal of your minds, that you may know what is God's will: what is good, pleasing and perfect."
This becomes the basis for all the Commandments, as the Lord details the kind of life he is talking about; the kind of life he himself desires for us. And after every topic, the refrain comes, "I am the Lord."
"....You shall not defraud or rob your neighbor.The Gospel takes that last line and changes it to, "You shall love your neighbor as Myself": "Whatsoever you do to the least, you do to me." Saul would discover this on the road to Damascus ("Why are you persecuting Me?") and it would change his life forever.
You shall not withhold overnight the wages of your day laborer.
You shall not curse the deaf,
or put a stumbling block in front of the blind,
but you shall fear your God.
I am the LORD.
"You shall not act dishonestly in rendering judgment.
Show neither partiality to the weak nor deference to the mighty,
but judge your fellow men justly.
You shall not go about spreading slander among your kin;
nor shall you stand by idly when your neighbor's life is at stake.
I am the LORD....
....You shall love your neighbor as yourself. I am the Lord."
