Hebrews 8:9-11, 13

It will be an entirely different covenant than the one I made with their fathers when I led them by my hand out of Egypt. For they did not remain faithful to my covenant, so I rejected them, says the Lord God. For here is the covenant I will one day establish with the people of Israel: I will embed my laws within their thoughts and fasten them onto their hearts. I will be their loyal God and they will be my loyal people. And the result of this will be that everyone will know me as Lord! There will be no need at all to teach their fellow-citizens or brothers by saying, ‘You should know YAHWEH,’ since everyone will know me inwardly, from the most unlikely to the most distinguished.

This proves that by establishing this new covenant the first is now obsolete, ready to expire, and about to disappear.
