One of the key elements in Leviticus 23, discussing the Feast of Tabernacles, is the wandering of Israel in Tabernacles, in physical tents that were temporary. This theme is carried out in the New Testament, where Paul in 2 Corinthians 4-5 reminds we tabernacle, we dwell, in temporary vessels... this more than any other reminds us that we know, once in the Kingdom, how it is to hurt.
