I would think that Sheol/Hades is the state/estate of death.
Well of all things a JW just came to the door. Went out and talked to him about my peppers growing in the flower bed in front yard.
Interesting.
Once again.
Because thou wilt not leave my soul in Hades, neither wilt thou suffer thine Holy One to see corruption. Thou hast made known to me (David) the ways of life; thou shalt make me full of joy with thy countenance. Men 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. A2:27,28,29
Therefore 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; He seeing this before spake of the resurrection of (the) Christ, :from A2:30,31
Where was the soul of David on this day?
I will answer, Dead in Hades, he was dead in faith, of the obedience of his seed Jesus, the Son of the Living God, unto death and being raised from the dead by God the Father of Jesus.
