Some Bible verses which prove that the Old Covenant ordainances are replaced by the New Covenant:

"Jesus answered them, "Destroy this temple, and in three days I will raise it up."  (John 2:19)

“Then what becomes of our boasting? It is excluded. On what principle? On the principle of works? No, but on the principle of faith.”  (Rom 3:27-28)  Paul speaking of the works of the old covenant laws.

“For sin will have no dominion over you, since you are not under law but under grace.” (Rom. 6:14)

“But now we are discharged from the law, dead to that which held us captive, so that we serve not under the old written code but in the new life of the Spirit.” (Rom 7:6)

“For Christ is the end of the law, that every one who has faith may be justified.” (Rom 10-4)

“Owe no one anything, except to love one another; for he who loves his neighbor has fulfilled the law. The commandments, "You shall not commit adultery, You shall not kill, You shall not steal, You shall not covet," and any other commandment, are summed up in this sentence, "You shall love your neighbor as yourself." Love does no wrong to a neighbor; therefore love is the fulfilling of the law. For we hold that a man is justified by faith apart from works of law.” (Rom 13:8-10)

“And you, who were dead in trespasses and the uncircumcision of your flesh,  God made alive together with him, having forgiven us all our trespasses,  having canceled the bond which stood against us with its
legal demands; this he set aside, nailing it to the cross. He disarmed the principalities and powers and made a public example of them, triumphing over them in him. Therefore let no one pass judgment on you in questions of food and drink or with regard to a festival or a new moon or a sabbath.” (Col. 1:13-16)

“In speaking of a new covenant he treats the first as obsolete. And what is becoming obsolete and growing old is ready to vanish away.” (Heb. 8:13)

“then he added, "Lo, I have come to do thy will." He abolishes the first in order to establish the second.” (Heb. 10:9)

“and to Jesus, the mediator of a new covenant, and to the sprinkled blood that speaks more graciously than the blood of Abel.” (Heb 12:24)

“For the whole law is fulfilled in one word, "You shall love your neighbor as yourself." (Gal. 5:14)

“So that the law was our custodian until Christ came, that we might be justified by faith.  But now that faith has come, we are no longer under a custodian;” (Gal 3:24-25)

“I do not nullify the grace of God; for if justification were through the law, then Christ died to no purpose.” (Gal 2:21)

“But their minds were hardened; for to this day, when they read the old covenant, that same veil remains unlifted, because only through Christ is it taken away.” (2Cor. 3:14)

“Behold, the days are coming, says the LORD, when I will make a new covenant with the house of Israel and the house of Judah, not like the covenant which I made with their fathers when I took them by the hand
to bring them out of the land of Egypt, my covenant which they broke, though I was their husband, says the LORD. But this is the covenant which I will make with the house of Israel after those days, says the LORD: I will put my law within them, and I will write it upon their hearts; and I will be their God, and they shall be my people. And no longer shall each man teach his neighbor and each his brother, saying, `Know the LORD,' for they shall all know me, from the least of them to the greatest, says the LORD; for I will forgive their iniquity, and I will remember their sin no more." (Jer. 31:31-34) Old Testament Prophesy of the new covenant.
