***That is interesting.****
The people promised to do all that God commanded.
Moses received the Commandments. the people were breaking them at the same moment.
Moses hurled them down and they were broken. Think of the symbolism in it.
Moses then must carve out a new set which are put into a gold plated coffin and carried before the people as an “IN YOUR FACE” reminder of their failure to keep their part of the covenant as it was now dead, by THEIR OWN hand.
I think that is one of the reasons the Commandments went into the ark. Our best efforts and our most sincere promises are frail, at best.
Don’t misunderstand me on one point. Let me be as clear as I can be. We are not saved by keeping the commandments. God has given us the gift of being able to come to Him unlimited number of times and ask for forgiveness, with the confidence that we will be forgiven. Even when our disobedience is planned.
