I was telling my son that the Bible doesn’t mention heaven or hell. Am I wrong?
i've heard people say this before, and unfortunately it's wrong. "heaven" is all over the place. the word "hell" is only used in the new testament, per the online bible i just consulted. in the old testament they used phrases like "the grave", "the pit", or "death" to mean a place of eternal damnation - but never the word "hell".
FWIW, neither book was written in english, so...
correct, but every culture touched by one of the Big Three monotheistic religions has a direct translation for the word "hell". so while the original hebrew, aramaic, greek, etc. texts would not have H + E + L + L they would have used their direct equivalent (or in the case of the old testament, not).
