Deuteronomy 29:23-24

and that the whole land thereof is brimstone, and salt, and a burning, that it is not sown, nor beareth, nor any grass groweth therein, like the overthrow of Sodom and Gomorrah, Admah and Zeboiim, which Jehovah overthrew in his anger, and in his wrath: even all the nations shall say, Wherefore hath Jehovah done thus unto this land? what meaneth the heat of this great anger?
