figure things out and finally became so frustrated that the Law was so hard to follow and
God kept sending them into captivity and there was so much death and eventually the prophets started prophesying about a day that would come where the hearts of the fathers would return to their children and a sacrifice that would be the
final sacrifice so that they could all stop killing so many animals (which
God also admitted He never wanted in the first place because that was not the point), and also that
God would eventually wipe out the old system and write his law on their hearts and minds so that they could finally follow him without making so many mistakes and messing up everything.
