It can not be argued with support that the old covenant was still in effect.
Matthew 5:18 For verily I say unto you,
Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be
fulfilled. (
ginomai = generated)
Matthew 24:34-35 Verily I say unto you, This generation shall not pass, till all these things be
fulfilled. Heaven and earth shall pass away, but My words shall not pass away.
Everlasting = OT owlam + NT aionios = perpetual (also used of past time, or past and future as well):--eternal,
for ever, everlasting... time out of mind, world without end.
Genesis 17:13 He that is born in thy house, and he that is bought with money shall be surely circumcised, and My covenant shall be on your flesh for an
everlasting covenant.
Isaiah 24:5 And she has sinned by reason of her inhabitants; because they have transgressed the law, and changed the ordinances, even the
everlasting covenant.
Isaiah 55:3 Give heed with your ears, and follow My ways: hearken to Me, and your soul shall live in prosperity; and I will make with you an
everlasting covenant, the sure mercies of David.
Isaiah 61:7-10 Thus shall they inherit the land a second time, and everlasting joy shall be upon their head. 8 For I am the Lord who love righteousness, and hate robberies of injustice; and I will give their labour to the just, and will make an
everlasting covenant with them. 9 And their seed shall be known among the Gentiles, and their offspring in the midst of peoples: every one that sees them shall take notice of them, that they are a seed blessed of God; 10 and they shall greatly rejoice in the Lord.
Jeremias 27:4-6 In those days, and at that time, the children of Israel shall come, they and the children of Juda together; they shall proceed, weeping as they go, seeking the Lord their God. 5 They shall ask the way till they come to Sion, for that way shall they set their face; and they shall come and flee for refuge to the Lord their God; for the
everlasting covenant shall not be forgotten. 6 My people have been lost sheep: their shepherds thrust them out, they caused them to wander on the mountains: they went from mountain to hill, they forgot their resting-place.
Jeremias 38:31-41 Behold, the days come, saith the Lord, when I will make a new covenant with the house of Israel, and with the house of Juda: 32 not according to the covenant which I made with their fathers in the day when I took hold of their hand to bring them out of the land of Egypt; for they abode not in My covenant, and I disregarded them, saith the Lord. 33 For this is My covenant which I will make with the house of Israel; after those days, saith the Lord,
I will surely put My laws into their mind, and write them on their hearts; and I will be to them a God, and they shall be to Me a people. 39:40 And I will make with them an
everlasting covenant, which I will by no means turn away from them, and I will put My fear into their heart, that they may not depart from Me. 41 And I will visit them to do them good, and I will plant them in this land in faithfulness, and with all My heart, and with all My soul.
John 14:26 But the Comforter, [which is]
the Holy Spirit, whom the Father will send in My name, He shall teach you all things, and
bring all things to your remembrance, whatsoever I have said unto you.

So there must be a different reason for why this happened:
Matthew 27:51-53 And, behold, the veil of the temple was rent in twain from the top to the bottom; and the earth did quake, and the rocks rent; 52 And the graves were opened; and many bodies of the saints which slept arose, 53 And came out of the graves after His resurrection, and went into the holy city, and appeared unto many.
Why were the graves opened, and they came out after His Resurrection? How does it make sense to anyone that this means the Law is finished, when the Law is co-eternal with the World that's controlled by the Law?
It is actually the defeat of the serpent which brought sin and death to the world. So that, Matthew 27:51-53 fulfills Genesis 3:15. In context, it also means that Jesus has become the Passover-Lamb/defender/advocate against the dragon... which will fight Michael, be cast down wounded...
