that's not completely correct they where left because they disobeyed,Yeah, it matters because God had no such covenant relationship with any other nation.
In the wilderness, the vast majority of the Jews were apostates, which is why they were forbidden to enter the Promised Land.
And it also proves he had a relationship with them.
Also they where judged by his inherent will in them. He had strengthened and willed there hearts with healthy fear, instead they disobeyed out of there's own will.
And your will right now is limiting God and just going in one direction.
Sorry to have to inform but it's because of people like you, the true good calvies have a bad name
