the second death

"dying a second time." This is described as eternal punishment in the lake of fire in Revelation 20:14 and Revelation 21:08. See how you translated this in Revelation 2:11. Alternate translation: "the final death in the lake of fire" (See: rc://en/ta/man/translate/writing-symlanguage)
