What happened to those three men? Good question, Bro. George.
That question came across my mind in Bible school but have not taken the time to seriously look into that until now.
But here's what I was thinking of. Maybe, just a GUESS, Enoch was taken to Abraham's bosom (paradise). Moses' was buried by God in an unknown graveyard and his soul brought to Abraham's bosom (paradise). I think Elijah was visibly taken up into heaven (the first heaven) and then taken to Abraham's bosom after that, instead of the third heaven.
