Rabbi Haninah (or some say Rabbi Joshua ben Levi) deduced from the words "the whole land thereof is brimstone, and salt" in that all the land of Israel was burned, and thus even wicked people buried in the land of Israel before that time will merit to be resurrected, because the burning of the land will have executed on them the punishment that justice demanded. A Baraita taught in the name of Rabbi Judah that the land of Israel burned for seven years.
