Here are a list of verses showing us the Old Law is no more:
"When God speaks of a "new" covenant, it means he has made the first one obsolete. It is now out of date and will soon disappear." (Hebrews 8:13) (NLT).
”Wherefore, my brethren, ye also are become dead to the law by the body of Christ; that ye should be married to another, even to him who is raised from the dead, that we should bring forth fruit unto God.” (Romans 7:4).
"But now we are delivered from the law, that being dead wherein we were held; that we should serve in newness of spirit, and not in the oldness of the letter." (Romans 7:6).
"Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross;" (Colossians 2:14).
20 "Wherefore if ye be dead with Christ from the rudiments of the world, why, as though living in the world, are ye subject to ordinances,
21 (Touch not; taste not; handle not;
22 Which all are to perish with the using; ) after the commandments and doctrines of men?
23 Which things have indeed a shew of wisdom in will worship, and humility, and neglecting of the body: not in any honour to the satisfying of the flesh."
(Colossians 2:20-23).
“By abolishing in His [own crucified] flesh the enmity [caused by] the Law with its decrees and ordinances [which He annulled]; that He from the two might create in Himself one new man [one new quality of humanity out of the two], so making peace.” (Ephesians 2:15) (AMPC).
"The old [former] rule [commandment; regulation] is now set aside [nullified; abolished], because it was weak and useless [ineffective]." (Hebrews 7:18) (EXB).
9 “Which was a figure for the time then present, in which were offered both gifts and sacrifices, that could not make him that did the service perfect, as pertaining to the conscience;
10 Which stood only in meats and drinks, and divers washings, and carnal ordinances, imposed on them until the time of reformation.” (Hebrews 9:9-10).
16 “For where a testament is, there must also of necessity be the death of the testator.
17 For a testament is of force after men are dead: otherwise it is of no strength at all while the testator liveth.” (Hebrews 9:16-17).
”And for this cause he is the mediator of the new testament…” (Hebrews 9:15).
27 “And he took the cup, and gave thanks, and gave it to them, saying, Drink ye all of it;
28 For this is my blood of the new testament, which is shed for many for the remission of sins.” (Matthew 26:27-28).
50 “Jesus, when he had cried again with a loud voice, yielded up the ghost.
51 And, behold, the veil of the temple was rent in twain from the top to the bottom; “ (Matthew 27:20-51).
8 “Above when he said, Sacrifice and offering and burnt offerings and offering for sin thou wouldest not, neither hadst pleasure therein; which are offered by the law;
9 Then said he, Lo, I come to do thy will, O God. He taketh away the first, that he may establish the second.” (Hebrews 10:8-9).
“And certain men which came down from Judaea taught the brethren, and said, Except ye be circumcised after the manner of Moses, ye cannot be saved.” (Acts of the Apostles 15:1).
“But there rose up certain of the sect of the Pharisees which believed, saying, That it was needful to circumcise them, and to command them to keep the law of Moses.” (Acts of the Apostles 15:5).
“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” (Acts of the Apostles 15:24).
28 "For it seemed good to the Holy Ghost, and to us, to lay upon you no greater burden than these necessary things;
29 That ye abstain from meats offered to idols, and from blood, and from things strangled, and from fornication: from which if ye keep yourselves, ye shall do well. Fare ye well." (Acts of the Apostles 15:28-29).
7 "But if the ministration of death, written and engraven in stones, was glorious, so that the children of Israel could not stedfastly behold the face of Moses for the glory of his countenance; which glory was to be done away:
8 How shall not the ministration of the spirit be rather glorious?
9 For if the ministration of condemnation be glory, much more doth the ministration of righteousness exceed in glory.
10 For even that which was made glorious had no glory in this respect, by reason of the glory that excelleth.
11 For if that which is done away was glorious, much more that which remaineth is glorious." (2 Corinthians 3:7-11).
“But their minds were blinded: for until this day remaineth the same vail untaken away in the reading of the old testament; which vail is done away in Christ.” (2 Corinthians 3:14).
The Old Covenant says this about circumcision:
"And the uncircumcised man child whose flesh of his foreskin is not circumcised, that soul shall be cut off from his people; he hath broken my covenant." (Genesis 17:14).
Yet, the New Covenant says this about circumcision:
"Behold, I Paul say unto you, that if ye be circumcised, Christ shall profit you nothing." (Galatians 5:2).
The Old Covenant says this about the Sabbath:
32 "And while the children of Israel were in the wilderness, they found a man that gathered sticks upon the sabbath day.
33 And they that found him gathering sticks brought him unto Moses and Aaron, and unto all the congregation.
34 And they put him in ward, because it was not declared what should be done to him.
35 And the Lord said unto Moses, The man shall be surely put to death: all the congregation shall stone him with stones without the camp.
36 And all the congregation brought him without the camp, and stoned him with stones, and he died; as the Lord commanded Moses." (Numbers 15:32-36).
Yet, the New Covenant says this about the Sabbath:
"Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days:" (Colossians 2:16).
So it appears things have changed.
This makes sense because Hebrews 7:12 says the Law has changed.
"For the priesthood being changed, there is made of necessity a change also of the law." (Hebrews 7:12).
“For the law was given by Moses, but grace and truth came by Jesus Christ.” (John 1:17).
In conclusion:
You sort of have to look at the Old Covenant (Old Testament) as one contract, and the New Covenant (New Testament) as another contract. It's kind of like a contract when you buy a house. If you did not like certain things in the contract, you could ask them to make some changes in the contract. If they agreed to the changes, you would then go by the new contract, and the old contract for the house would be discarded. There may be some similar things between the old contract, and the new contract, but you stick with the new contract in your dealing with buying the house. Meaning: This is why we seek to follow the New Covenant (New Testament) primarily even though there are certain laws that have carried over from the Old Covenant (Old Testament). We are clearly not under the 613 Laws of Moses as a whole or package deal. We follow the commands that come from Jesus and His followers.
