Midrasch zu Jechezkiel 16:48

And thus do you find with the men of Sodom, that they rebelled only out of satiety, it being written of them (Job 28:5) "a land from which bread came forth, and whose place was overturned as with fire." The men of Sodom said: "We have food; we have silver and gold. Let us arise and banish the law of hospitality from our midst" — to which the L-rd responded: "With the good that I have bestowed upon you, you want to banish the law of hospitality from your midst? I shall banish you from the world!" What is written of them? (Ibid. 4) "A stream (of fire and brimstone) burst forth from its source (upon Sodom), who (i.e., the people of Sodom) caused the (code of the) wayfarer to be forgotten." (Ibid. 12:5-6) "The torch of (the) shame (of Gehinnom awaits) him who is at ease in (his) thoughts, (saying: "I shall be at peace,") (and that he is) prepared (to join the ranks of) those whose foot slips. The tents of robbers are at peace, and those who anger G-d dwell secure, (and with all) that G-d has brought (to the evildoer, the 'hour' plays into) his hand." And this is the intent of (Ezekiel 16:48-50) "Behold, this was the sin of Sodom your sister. She and her daughter had pride, surfeit of bread and peaceful serenity; but she did not strengthen the land of the poor and the needy. And they grew presumptuous and committed abomination before Me, and I removed them (from the world) when I saw (their ways)."
