I have given a full break down a number of times here.
I will sum it up.
This was about entering the congregation. In those days IT WAS NOT COME AS YOU ARE. They were very strict, if you think this is all one had to do, this is it!!!!! that is silly We can do any other foul thing just not strangle animals with blood. LOL really. No this was the starting point.
explain why a select few "laws" are chosen to follow but not all?
20 But rather, write to them that they abstain from defilements: such as idolatry, from all sexual impurity, from that which has been cooked with the blood still in it, and from bloodshed by violence
20 But that we write unto them, that they abstain from pollutions of idols, and from fornication, and from things strangled, and from blood.
Act 15:23,24 "And they wrote letters by them after this manner; The apostles and elders and brethren send greeting unto the brethren which are of the Gentiles in Antioch and Syria and Cilicia:
forasmuch as we have heard, that certain which went out from us have troubled you with words, subverting your souls, saying, Ye must be circumcised,
and keep the law:
to whom we gave no such commandment"
Judas and Silas were both 'prophets' as well in this assembly of the Jewish believers in Messiah, thus fulfilling what Paul said in Eph 4:11 - in the order that he gave these offices in. All 5 of these offices were represented at that 'meeting'.
This much I will say to what your reply implies to me ...
Matthew 19:16-19 And, behold, one came and said unto him,
Good Master, what good thing shall I do, that I may have eternal life?
And he said unto him, Why callest thou me good? there is none good but one, that is, God:
but if thou wilt enter into life, keep the commandments.
He saith unto him, Which? Jesus said, Thou shalt do no murder, Thou shalt not commit adultery, Thou shalt not steal, Thou shalt not bear false witness, honour thy father and thy mother: and, Thou shalt love thy neighbour as thyself.
Mark 10:17,19 And when he was gone forth into the way, there came one running, and kneeled to him, and asked him, Good Master, what shall I do that I may inherit eternal life?
[Jesus answered] Thou knowest the commandments, Do not commit adultery, Do not kill, Do not steal, Do not bear false witness, Defraud not, Honour thy father and mother.
Luke 18:18, 20 And a certain ruler asked him, saying, Good Master, what shall I do to inherit eternal life? [Jesus answered] Thou knowest the commandments, Do not commit adultery, Do not kill, Do not steal, Do not bear false witness, Honour thy father and thy mother.
Eph 6:2,3 Honour thy father and mother; (which is the first commandment with promise) that it may be well with thee, and thou mayest live long on the earth.
Mat 15:3-14 But he answered and said unto them, Why do ye also transgress the commandment of God by your tradition?
For God commanded, saying, Honour thy father and mother: and, He that curseth father or mother, let him die the death. But ye say, Whosoever shall say to his father or his mother, It is a gift, by whatsoever thou mightest be profited by me; and honour not his father or his mother, he shall be free. Thus have ye made the commandment of God of none effect by your tradition.
Ye hypocrites, well did Esaias prophesy of you, saying, this people draweth nigh unto me with their mouth, and honoureth me with their lips; but their heart is far from me.
But in vain they do worship me, teaching for doctrines the commandments of men.
And he called the multitude, and said unto them, Hear, and understand:
Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man.
Then came his disciples, and said unto him, Knowest thou that the Pharisees were offended, after they heard this saying?
But he answered and said, Every plant, which my heavenly Father hath not planted, shall be rooted up.
Let them alone: they be blind leaders of the blind. And if the blind lead the blind, both shall fall into the ditch.

So Jesus is answering us as well but it doesn't include the 613 but the Moral law/the 10 Commandments and the Royal Law of Loving GOD with all of our hearts, souls, minds, with all of our strength and might and loving ALL as we [do] love ourselves - Acts 15:24 = the Jews were not forbidden to observe the Feasts, the Saturday Sabbath, nor the moral law - but the animal Sacrifices are fulfilled in Christ - as were all of the laws fulfilled were in Him - but that doesn't mean that we do not have our Commandments from Him in the entire New Covenant.
So, we do not stone our unruly children, etc. nor treat people with an issue of blood, etc in the ways commanded in the Torah.
The majority of the 613 were types and figures/shadows and a school master to lead them/us to The Messiah/Christ.
After we are filled with His Spirit, upon true Salvation by grace through faith - we are to rightly divide The Word of Truth 'that is written' in the/His New Covenant ... every jot and tittle of it - Amen!
The whole of His Book is meaningful and Sacred to us - but we'll never understand the Old 'Testament' until we've fully eaten/digested the whole of the New and have been led by His Spirit of Truth [John 16:13] to know and understand every Word written therein.
Unless we reverence His New Covenant with all our heart, soul, mind and strength - we will not fulfill the Commandments that He speaks of from Matthew to the Revelation that we'll be judged by ... one of the Books [plural] opened at the Judgment, besides the Lamb's Book of Life.
