“And turning the cities of Sodom and Gomorrha into ashes condemned them with an overthrow, making them an ensample unto those that after should live ungodly;”
King James Version (KJV)
2:4 Cast them down to hell - The bottomless pit, a place of unknown misery. Delivered them - Like condemned criminals to safe custody, as if bound with the strongest chains in a dungeon of darkness, to be reserved unto the judgment of the great day. Though still those chains do not hinder their often walking up and down seeking whom they may devour.
2:5 And spared not the old, the antediluvian, world, but he preserved Noah the eighth person - that is, Noah and seven others, a preacher as well as practiser, of righteousness. Bringing a flood on the world of the ungodly - Whose numbers stood them in no stead.
2Pe 2:6 Turning the cities of Sodom and Gomorrha into ashes. The third example of judgment on sin. See Ge 19:29.
