No confusion. The lake of

fire is hell.
''The lake of fire, mentioned only in Revelation 19:20 and 20:10, 14-15, is the final hell, the place of eternal punishment for all unrepentant rebels, both angelic and human (Matthew 25:41). It is described as a place of burning sulfur, and those in it experience eternal, unspeakable agony of an unrelenting nature (Luke 16:24; Mark 9:45-46). Those who have rejected Christ and are in the temporary abode of the dead in hades/sheol have the lake of fire as their final destination. But those whose names are written in the Lamb’s book of life should have no fear of this terrible fate. By faith in Christ and His blood shed on the cross for our sins, we are destined to live eternally in the presence of God.
