In the book of Hebrew it is clear that there was an end to the covenant and new one was formed through Christ, but only for those who accept Him as the Lord.

For finding fault with them, behold, the days come, saith the Lord when I will make a new covenant with the House of Israel and the House of Judah: Not according to the covenant that I made with their fathers, in the day when I took them by the end out of the land of Egypt; because they continued not in my covenant, and I regarded them not, saith the Lord. [Hebrews 8:6-7, 9-10]

Therefore I tell you, the kingdom of God will be taken away from you and given to a nation producing the fruits of it. And when the chief priests and Pharisees heard his parables, they perceived that he spoke of them. [Matthew 21:43-45]
Those those who believe in Christ and the New Testament, cannot deny that the so-called covenant has been taken away from the Jews.

Please reread the first sentence of the Scripture you reference;

"For finding fault with them, behold, the days come, saith the Lord when I will make a new covenant with (who?) the House of Israel and the House of Judah...."

Also, verse 10 in that same chapter says "For this [is] the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people."

The Apostle Paul is talking to the Jews in this and earlier chapters explaining to them that there was no longer the need for sinful men to be priests/intercessors for the people before God, because Jesus had now become the their high perfect priest, the one and only true intercessor between man and God the Father. This Scripture has nothing to do about God taking away His covenant with the nation of Israel being His chosen people.
