No, Psalm 40 is David's deliverance while in this life.
Job 33 speaks to how to keep ones self free of the pit. A teaching to the living.
The Book of Jonah, one of the minor prophet books we should note, and chapter 2 is Jonah's prophecies. The whale vomiting Jonah on dry land is not Jonah arriving at Nineveh ,as God had told him to travel there in the beginning, because Nineveh is located on the Tigris.
Where are the verses that say the living are able to enter Sheol?
Jonah was dead. David was not. Nor was Job, just to throw that in there.
Consider the comparison. Huge storm, Jonah thrown overboard by those on the ship thinking it would save them from the storm, Jonah swallowed by a great fish, some say whale,
but it was the belly of Sheol, where he stayed for three days as one dead, think Jesus there and His three days in the tomb, the body dead, the spirit departed to minister unto those in Sheol, then he's vomited on the dry land and seemingly learns not to doubt God's orders and do what he's told for the people of Nineveh. Which Jonah concedes to and does go there.
Then Jonah questions God's intention to spare the people of Nineveh. As if he didn't learn his lesson after being covered with big fish bile? The only prophet in the old testament sent by God directly to the Gentiles, and Jonah still has his own temperament and will?
Nineveh repented, God withheld his wrath.
Jonah is 4 chapters long.
Jonah's Anger and the Lord's Compassion
The Book of Jonah chapter 4 But it displeased Jonah exceedingly,[
a] and he was angry. 2 And he prayed to the Lord and said, “O Lord, is not this what I said when I was yet in my country? That is why I made haste to flee to Tarshish; for I knew that you are a gracious God and merciful, slow to anger and abounding in steadfast love, and relenting from disaster. 3 Therefore now, O Lord, please take my life from me, for it is better for me to die than to live.” 4 And the Lord said, “Do you do well to be angry?”
5 Jonah went out of the city and sat to the east of the city and made a booth for himself there. He sat under it in the shade, till he should see what would become of the city. 6 Now the Lord God appointed a plant[
b] and made it come up over Jonah, that it might be a shade over his head, to save him from his discomfort.[
c] So Jonah was exceedingly glad because of the plant. 7 But when dawn came up the next day, God appointed a worm that attacked the plant, so that it withered. 8 When the sun rose, God appointed a scorching east wind, and the sun beat down on the head of Jonah so that he was faint. And he asked that he might die and said, “It is better for me to die than to live.” 9 But God said to Jonah, “Do you do well to be angry for the plant?” And he said, “Yes, I do well to be angry, angry enough to die.” 10 And the Lord said, “You pity the plant, for which you did not labor, nor did you make it grow, which came into being in a night and perished in a night.
11 And should not I pity Nineveh, that great city, in which there are more than 120,000 persons who do not know their right hand from their left, and also much cattle?”

[*][c]Jonah 4:6 Or his evil
To think Jonah was alive as himself in Sheol one has to show those scriptures that inform us the full living flesh, human with their soul, is able to go to the place of the dead, and then return back to life. And when we are told the Rephaim, the spirits of the departed dead, reside there.
