A lot of references might be overstating it. I think most of the references, particularly to heaven/Abraham’s Bosom are not that clearly referencing heaven. Some of them are used as references to heaven when they are cited in the New Testament. But, if you reject all things NT, then you wouldn’t change how you read those verses based on how they were used in the NT. Just like protestants don’t give a shit how Catholics or Mormons view verses in light of their additional texts.
