From failed prophecies in matthew:

Where Christians and Atheists disconnect is that the culture of ancient Judaism was not like modern American culture. In order to show events were true or from God, they were compared with parallel concepts. The concepts did not have to be exact or a prophecy (as Americans think of prophecy: foretelling future events). The point was more to show precedence: to show that God was doing something in the New Testament, the Old Testament was shown to have a similar concept. The apostle Paul is known to do this (see Romans 9:25 v Hosea 1:10 and 2:23). Matthew does this to no end, infuriating critics of Christianity.
