‘To our fathers’, to whom the great promises concerning Israel were first made when God promised that they would be his people and he would be their God. That promise to the nation formed the basis of all his further dealings with them until that time.
There is nothing like the prophecy of the Bible in human history. No one has ever been prophesied apart from Jesus Christ. These prophesies were give thousands of years before he came and they were not vague predictions like the phoney prophecies; God was spelling out the details: how he would be buried and rise. Scarcely a detail of his life and ministry was not made clear long before he came.
