Behold, for peace I had great bitterness: but thou hast in love to my soul delivered it from the pit of corruption: for thou hast cast all my sins behind thy back.(Isaiah 38:17-18) KJV
For the grave cannot praise thee, death can not celebrate thee: they that go down into the pit cannot hope for thy truth.
Our spherical hollow earth model (SHEM) is compatible with everything the Bible says pertaining to how its form fits its function. The function of the pit is to hold the souls of the lost until the final judgement.
