John Wesley on Genesis 19:25

And he overthrew the cities, and all the inhabitants of them, the plain, and all that grew upon the ground - It was an utter ruin, and irreparable; that fruitful valley remains to this day a great lake, or dead sea. Travelers say it is about thirty miles long, and ten miles broad. It has no living creature in it: it is not moved by the wind: the smell of it is offensive: things do not easily sink in it. The Greeks call it Asphaltis, from a sort of pitch which it casts up. Jordan falls into it, and is lost there. It was a punishment that answered their sin. Burning lusts against nature were justly punished with this preternatural burning.
