Midrash su Salmi 52:9

Rabbi Ẓe'era said: The men of Sodom were the wealthy men of prosperity, on account of the good and fruitful land whereon they dwelt. For every need which the world requires, they obtained therefrom. They procured gold therefrom, as it is said, "And it had dust of gold" (Job 28:6). What is the meaning (of the text), "And it had dust of gold"? At the hour when one of them wished to buy a vegetable, he would say to his servant, Go and purchase for me (for the value of) an assar. He went and bought (it), and found beneath it heaps of gold; thus it is written, "And it had dust of gold" (ibid.). They obtained silver therefrom, as it is said, "Surely there is a mine for silver" (Job 28:1). They procured precious stones and pearls thence, as it is said, || "The stones thereof are the place of sapphires" (Job 28:6). They obtained bread therefrom, as it is said, "As for the earth, out of it cometh bread" (Job 28:5). But they did not trust in the shadow of their Creator, but (they trusted) in the multitude of their wealth, for wealth thrusts aside its owners from the fear of Heaven, as it is said, "They that trust in their wealth" (Ps. 49:6).
