Everyone in the Old Testament who died, went to Hell: Abraham, Moses, David, everyone.
But the ones who were saved (such as Abraham, Moses, and David) went to the Paradise side.
That's why, in the Old Testament, the witch of Endor had to call Abraham up from Paradise.
In the New Testament, Jesus took Paradise to Heaven.
That is why, when Paul was beaten to death at Lystra (Acts 14), he talks about seeing Paradise in Heaven.
2 Corinthians 12:1 It is not expedient for me doubtless to glory. I will come to visions and revelations of the Lord.
2 I knew a man in Christ above fourteen years ago, (whether in the body, I cannot tell; or whether out of the body, I cannot tell: God knoweth: ) such an one caught up to the third heaven.
3 And I knew such a man, (whether in the body, or out of the body, I cannot tell: God knoweth: )
4 How that he was caught up into paradise, and heard unspeakable words, which it is not lawful for a man to utter.
