First familiarize yourself with the story here.
For the next several weeks I will publish one paragraph from the sermon On Naboth given by St. Ambrose. The entire text may be found here.
1.2. How far, O rich, do you extend your mad greed? ‘Shall you alone dwell upon the earth’ (Isa. 5:8). Why do you cast out the companion whom nature has given you and claim for yourself nature’s possession? The earth was established in common for all, rich and poor. Why do you alone, O rich, demand special treatment? Nature, which begets everyone poor, knows no wealthy, for we are not born with clothing or begotten with gold and silver. Naked it brings us into the light (cf. Job 1:21), wanting food, clothing and drink, and naked the earth receives us whom it brought forth, not knowing how to compass our possessions in the tomb. The narrow sod is equally spacious for poor and rich, and the earth, which did not contain the desires of the rich person when he was alive, now contains him entirely. Nature, then, knows no distinction when we are born, and it knows none when we die. It creates all alike, and all alike it encloses in the bowels of the tomb. What differences can be seen among the dead? Open up the earth and, if you are able, discern who is rich. Then clear away the rubbish and, if you recognize the poor person, show who he is apart, perhaps, from this one fact alone—that more things perish with the rich.
