Sorry, that is incorrect.

Many references to "Sheol" would not make sense if it meant "Hell".

"The LORD kills and makes alive; He brings down to Sheol and raises up." (1 Sam 2:6)

"For You will not abandon my soul to Sheol; Nor will You allow Your Holy One to undergo decay." (Ps 16:10)

"O LORD, You have brought up my soul from Sheol; You have kept me alive, that I would not go down to the pit." (Ps 30:3)

"For Your lovingkindness toward me is great, And You have delivered my soul from the depths of Sheol." (Ps 86:13)

and he said, "I called out of my distress to the LORD, And He answered me I cried for help from the depth of Sheol; You heard my voice." (Jon 2:2)
