Deut 32
>he said to them, “Take to heart all these words I am giving as a warning to you today, so that you may command your children to carefully follow all the words of this law. 47 For they are not meaningless words to you but they are your life, and by them you will live long in the land you are crossing the Jordan to possess.”

I respectfully disagree. The law matteted more than anyth8ng to them. Refusal to follow it is what caused God to divorce them and semd them into captivity. Why would thry let their king be cursed?
