There is a misconception among some that if YHWH our creator makes a new covenant, then the covenants he had before are done away with.
He has many covenants that he has made to mankind and to certain people. Also when he says a covenant shall be an everlasting covenant, that means it does not end.
If me and you make a covenant we can obviously make other covenants and that doesn't cancel out our other covenant, whatever it may be.
So here is 1 scripture that clearly shows YHWH has more than 1 covenant at a time;
Deuteronomy 29:1 "These are the words of the covenant that YHWH commanded Moses to make with the people of Yisrael in the land of Moab, apart from the covenant that he had made with them at Horeb"
