How do you come up with that?
Colossians 2:17 "These are a shadow of the things to come, but the body that casts it belongs to Christ". Hebrews 8:5 "They serve a copy and shadow of what is in heaven." Hebrews 10:1 "For the law is only a shadow of the good things to come, not the realities themselves".

I read Cahn's book so I could explain this to people. It is not that difficult to understand. In addition to shadow and types we have archetypes, homiletics, symbolic, paradigms, parables, allusion and so on. The Bible is literal first then symbolic. The Hebrew letters are symbolic. Each stroke of the pen to create a Hebrew letter is symbolic. This is why Jesus says: "Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled." (Matthew 5:18)
There are six hundred thousand letters (jot & tittle) in the Torah. Israel did not leave Egypt until there were 600,000 of them. Everything is exact and precise and has a meaning for us today. I know pastors that can teach the symbolic meaning of every tiny detail we read about the temple in the Bible. This all has meaning for us today.
