Hi again, I'm going to give my 2 cents if you don't mind. But this knowledge is from the New Testament, so you may not want to accept it. Anyway, if you care what I believe - there was nothing wrong with the Ten Commandments; it was holy. What changed was the need for the written laws on stone. You see, the reason for the Law being given in the first place had to do with sin. You know that after Adam sinned, we all inherited the nature of the serpent, Satan. So sin dwells inside all of us from birth as part of our nature. If you know them, you can keep the letter of the law, but coveting goes deeper, and actually shows us we are sinners, no matter how we try to keep the law perfectly.
That is the reason why they gave sacrifices, but the blood of bulls and goats could only cover sin, not take it away. That is why Jesus came. His blood took away that old sin nature, and wrote the laws of God on our recreated nature. Therefore instead of man obeying laws contrary to his nature, he now could keep them naturally. But to do that, one must accept Jesus as their Savior from sin, and at least as the Son of God. Then God's Spirit can come inside of them, and abide inside of us, giving us His divine power and divine nature. Then we are no longer sinners, but children of God. You won't find many people on here (Christians) agreeing with me, but that is what the New Testament says, including the prophecy of the New Covenant in Jeremiah 31
