I would never ignore the word of the Lord whose commandments are good, clear and unequivocal as is the sixth commandment. This brings us back to what I was saying originally that the 613 Mitzvah Laws are the Priestly Code that was written by the Levite Priests and which were so closely followed by the Pharisees and Sadducees. Here is an example of how the word of the Lord evolved into the word of man and this is why I say we need to distinguish between the law of man and the law of God.
(Mak. ii. 2, 8a).
"Any one who neglects the necessary precautions in a courtyard or a shop, so that a person entitled to admittance there is killed, can not atone by going to the city of refuge [i.e., banishment is not sufficient] (B. Ḳ. 32b); but if he who was killed was a trespasser and had no right in such a court or shop, the owner goes free, as he can not be held responsible for accidents on his private property when he did not anticipate the possible presence of strangers"
Here is Jesus in Matthew 5 making the distinction between God's Law, religious law and the Law of Moses (Moses was from the tribe of Levi and as a result the Priestly Law has become known as the Law of Moses.)
“Don’t misunderstand why I have come. I did not come to abolish the law of Moses or the writings of the prophets. No, I came to accomplish their purpose. I tell you the truth, until heaven and earth disappear, not even the smallest detail of God’s law will disappear until its purpose is achieved. So if you ignore the least commandment and teach others to do the same, you will be called the least in the Kingdom of Heaven. But anyone who obeys God’s laws and teaches them will be called great in the Kingdom of Heaven.
“But I warn you—unless your righteousness is better than the righteousness of the teachers of religious law and the Pharisees, you will never enter the Kingdom of Heaven!
“You have heard that our ancestors were told, ‘You must not murder. If you commit murder, you are subject to judgement. ’But I say, if you are even angry with someone, you are subject to judgement! If you call someone an idiot, you are in danger of being brought before the court. And if you curse someone, you are in danger of the fires of hell….
But I say unto you - Jesus being God as well as man John 1:1, John 1:14, and therefore, being the original giver of the law (Jesus is creator God Colossians 1:16; John 1:3 had a right to expound it or change it as he pleased. Compare Matthew 12:6, Matthew 12:8. He therefore spoke here and elsewhere as having authority, and not as the scribes. It may be added here that no mere man ever spoke as Jesus did, when explaining or enforcing the law. Jesus did it as having a right to do it; and he that has a right to ordain and change laws in the government of God must be himself divine. (Barnes)
