'Lake' in the Bible

The beast was captured, along with the false prophet who had performed signs on its behalf. By these signs the false prophet had deceived those who had received the mark of the beast and worshipped its image. Both of them were thrown alive into the lake of fire that burns with sulfur.

and the Devil who deceived them was thrown into the lake of fire and sulfur, where the beast and the false prophet were. They will be tortured day and night forever and ever.

Death and Hades were thrown into the lake of fire. (This is the second death the lake of fire.)

Anyone whose name was not found written in the Book of Life was thrown into the lake of fire.

But people who are cowardly, unfaithful, detestable, murderers, sexually immoral, sorcerers, idolaters, and all liars will find themselves in the lake that burns with fire and sulfur. This is the second death."
