Paul said the 12 Apostles were promised reward in Heaven by Jesus not everyone. Them and the 144000
19 Therefore, brothers, since we have boldness* for the way of entry into the holy place+ by the blood of Jesus,20 which he opened up* for us as a new and living way through the curtain,+ that is, his flesh,
13 Moreover, no man has ascended into heaven+ but the one who descended from heaven,+ the Son of man.
So David,Moses and Noah didn't go and they were before that scripture was written.
