King david is not in heaven today, why would moses be ?, why would anyone be ? the bigger question if david is not in heaven where is he ?
29Men and brethren, let me freely speak unto you of the patriarch David, that he is both dead and buried, and his sepulchre is with us unto this day. 30Therefore being a prophet, and knowing that God had sworn with an oath to him, that of the fruit of his loins, according to the flesh, he would raise up Christ to sit on his throne; 31He seeing this before spake of the resurrection of Christ, that his soul was not left in hell, neither his flesh did see corruption. 32This Jesus hath God raised up, whereof we all are witnesses. 33Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this, which ye now see and hear.
34For David is not ascended into the heavens: but he saith himself, The LORD said unto my Lord, Sit thou on my right hand,
