Start debating what is the Biblical view of hell

I’d like to start with what the Old Testament says.

In the OT, the transliterated Hebrew word is Sheol. In the KJV, it is translated grave (31x), hell (31x), pit (3x). It has a range of meaning from a physical grave, or a physical pit, or a spiritual place where people go in the afterlife.

The original Jewish belief in Sheol was everyone went there in the afterlife.

“Sheol is a place of darkness to which all the dead go, both the righteous and the unrighteous, regardless of the moral choices made in life.”

All his sons and daughters came to comfort him, but he [Jacob] refused to be comforted. “No,” he said, “in mourning will I go down to the grave [Sheol] to my son.” So his father wept for him.
Genesis 37:35

There are indications Sheol was not the ultimate destination.

But God will ransom my soul from the power of Sheol, for He will receive me.
Psalm 49:15
