The reliability of tradition

I read what you wrote about the reliability of tradition. In my opinion, there are many promises in the Bible that did not happen (I think this can be proven. I am not sending you a list because you will refer me to the biblical scholars.) I would like to ask you whether such a thing does not harm the reliability of tradition, whether the prophecies spoken by the moralists of tradition were false? Besides, in the chain of Kabbalah that Maimonides cites, there is a break of many years between Baruch ben Neriah and Ezra. Doesn’t this harm tradition?
