The use of the law of Moses is a matter of utility to identify the law in question not to give Moses ownership over it. I'm sure you already knew this, so there's need to address this further.
There is ambiguity in the word "law" so I can try and use Torah to represent the first 5 books so there is no confusion (which is its proper name anyway)
The 10 commandments are a part of Torah and they do not stand alone. To invoke one is to invoke all it and there's no biblical precedence to separate the 10 outside of the Torah. So when a verse is used to support the 10 it must also be used to support the whole Torah.
The Ten Commandments are what hangs
on all of God's Word- love to God, love to man. Mat 22:40
I appreciate your opinion, but I am going to stick with what God's Word says:
Can you please tell me how many commandments are in God's covenant? I think God would know, sine He personally wrote them.
Deut 4:13 So He declared to you His covenant which He commanded you to perform,
the Ten Commandments; and He wrote them on two tablets of stone.
After God alone wrote the Ten Commandments- He added no more
Deut 5:22 22 “These words the Lord spoke to all your assembly, in the mountain from the midst of the fire, the cloud, and the thick darkness, with a loud voice
; and He added no more. And He wrote them on two tablets of stone and gave them to me.
Only the Ten Commandments was placed
inside the ark of the Covenant. Exo 40:20
I don't think its a good idea to add what's not there.
When you quote "blessed are those who do his commandments..." and conflat this with the 10 you are invoking the entire Torah with it.
Yes, if you read the next verse what commandments are being quoted from directly. It really helps our understanding if we allow God's Word to interpret Itself. It does not need our help and our opinions while important to us, do not equal His Word.
Revelation 22:14 Blessed
are those who do His commandments, that they may have the right to the tree of life, and may enter through the gates into the city. 15 But
outside are dogs and sorcerers (Breaking commandment #1
Exodus 20:3) and sexually immoral (breaking commandment #7
Exodus 20:14) and murderers (breaking commandment #6
Exodus 20:13) and idolaters (breaking commandment #2
Exodus 20:4-6), and
whoever loves and practices a lie (breaking # 9
Exodus 20:16). Which are any of the commandments 1 John 2:4 The commandments are a unit of Ten
Exodus 34:28 we break one commandment we break them all.
James 2:10-12
Jesus does a similar approach in Mathew 5. He quotes from some of the 10 but he also quotes outside the 10 as well, his point is clearly broader than the 10 itself. His method is similar in each saying "you have heard it said..." "But I say..." In this he shows how the law was limited and how a new covenant understanding views these values which is focused on Christ's law, the law of love. I may not sleep with my neighbors wife, murder him, steal from him, or covet his belongings, etc... but I also may hate him at the same time. In doing this I keep the 10 but Christ tells reminds me I've missed the point
Jesus said this:
Matthew 5:19 Whoever therefore breaks one of the least of these commandments, and teaches men so, shall be called least in the kingdom of heaven; but whoever does and teaches
them, he shall be called great in the kingdom of heaven.
He then made a statement about it, that our righteousness needs to
exceed the righteousness of the Pharisees, v20 and He condemned them for following their own rules over obeying the commandment of God again quoting directly from the Ten Commandments mat 15:3-14
then He proceeded to quote the commandments He was referring to by "least of these commandments"
Jesus is not giving permission to commit adultery and break these commandments as long as one does not have anger in their heart- He is trying to address sin where it starts - in the heart- right where God placed His law Heb 8:10 not only should we not break the literal commandment- but we should also not have thoughts that lead one to breaking them. Jesus did not say "But I say, you no longer need to keep the commandment to thou shalt not murder" that's nowhere in the text, so we should not add what's not there.
21 “You have heard that it was said to those [
d]of old, ‘You shall not murder, and whoever murders will be in danger of the judgment.’ 22 But I say to you that whoever is angry with his brother [
e]without a cause shall be in danger of the judgment. And whoever says to his brother, ‘Raca!’[
f] shall be in danger of the council. But whoever says, [
g]‘You fool!’ shall be in danger of [
h]hell fire. 23 Therefore if you bring your gift to the altar, and there remember that your brother has something against you, 24 leave your gift there before the altar, and go your way. First be reconciled to your brother, and then come and offer your gift. 25 Agree with your adversary quickly, while you are on the way with him, lest your adversary deliver you to the judge, the judge hand you over to the officer, and you be thrown into prison. 26 Assuredly, I say to you, you will by no means get out of there till you have paid the last penny.
27 “You have heard that it was said [
i]to those of old, ‘You shall not commit adultery.’ 28 But I say to you that whoever looks at a woman to lust for her has already committed adultery with her in his heart. 29 If your right eye causes you to [
j]sin, pluck it out and cast
it from you; for it is more profitable for you that one of your members perish, than for your whole body to be cast into hell. 30 And if your right hand causes you to [
k]sin, cut it off and cast
it from you; for it is more profitable for you that one of your members perish, than for your whole body to be cast into hell.
After He clarified what "these commandments" are He said
FUTHERMORE- which means in addition to
31 “Furthermore it has been said, ‘Whoever divorces his wife, let him give her a certificate of divorce.’ 32 But I say to you that whoever divorces his wife for any reason except [
l]sexual immorality causes her to commit adultery; and whoever marries a woman who is divorced commits adultery.
Then He relates divorce with the commandment of adultery because there is no law that does not have an umbrella under God's perfect law of Liberty.
