No, He took away Saturday sabbath keeping under the New Covenant where sabbath became far more than just resting and worshiping on Saturday.
2 rest in Hebrews 4 not one. The rest which is the Gospel and the seventh day Sabbath rest. They are not the same.
How do we know?
The works for the Gospel rest were finished from the foundation of the world. For God had rested from all His works. Which include the rest which is the Gospel according to verse three's usage of the word although. It says that He spake in a certain place. The only time the Seventh day was spoken by God was on Mt Sinai in the giving of the Commandments.
Verse 5 says in this again. In this again what? In this again He speaks of the seventh day if they shall enter into His rest which is the Gospel.
How does He speak?
Verse 9 and 10 tell tells us. It says there remains therefore a Sabbath Keeping to the people of God. For He that has entered in His rest which is the Gospel also in addition to this rest Also ceases from his own work as God did from His.
As God did from His is a direct comparison. Did God enter into the rest of salvation in Christ? No!
Heb 4:3 For we which have believed do enter into rest, as he said, As I have sworn in my wrath, if they shall enter into my rest: although the works were finished from the foundation of the world.
Heb 4:4 For he spake in a certain place of the seventh day on this wise, And God did rest the seventh day from all his works.
Heb 4:5 And in this again, If they shall enter into my rest.
Heb 4:9 So there remains a Sabbath-keeping for the people of God. (Footnote: aThe Greek word is sabattismos, which means Sabbath-keeping.)
Heb 4:10 For the one, having entered into His rest, has himself also rested from his works, as God rested from His own.
The religious nuts did not know Who Jesus was (they should have) so they thought He sinned by doing good works on the sabbath.
Agreed
Specifically... which part of Mathew 24 exactly?
Many Christian denominations make a division in Matthew 24. There is no division in Jesus' answer to the three question in verse 3.
Verse 20's praying that our flight not be in the winter nor the Sabbath is connected to all of it my friends by the use of the conjunctive particles, for, and, for. wherefore, for, for and, and respectively. This means that Jesus expected His follows to be keeping the Sabbath until His return. And the adverb "then" in verse 24 shows us that what is about to be said relies on what was previously stated. Verse 26's use of the particle "wherefore" shows us that what is about to be said is connected to verse 24. The context also makes this apparent. Then with the continuous use of the particle "for" in verses 27 and 28 coupled with the particle "and" in verses 30 and 31 we are shown what is about to be said is directly connected to what was said the whole way back to verse 4 actually. So as was said Jesús expected and therefore expects His follows to be keeping the Sabbath up through the destruction of the Temple through the tribulation prior to and up to His Second coming and the gathering of the elect from the four winds, from one end of Heaven unto the other.
Matt 24:20
But pray ye that your flight be not in the winter, neither on the sabbath day:
Matt 24:21
For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be.

Matt 24:27
For as the lightning cometh out of the east, and shineth even unto the west; so shall also the coming of the Son of man be. Matt 24:28
For wheresoever the carcase is, there will the eagles be gathered together.
Matt 24:29
Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:
Matt 24:30
And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.

And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.
