WE can say that IF you promise someone something you will do that YOU know you will never actually do - you lied
IF a god is All knowing - past - present - and future - that means that if MUST fulfill everything it says - it cannot CHANGE its mind. Changing its mind is the equivalent of not completing that promise
So the claim of a New Covenant REPLACING the old is an admission that the god LIED about the original covenant - since it HAD TO KNOW it as not going to actually fulfill the old covenant.
Again - this is an example of the contradictions of the claims of a god that cannot all be true at the same time.
