Midrasch zu Esra 2:66

“A man…went” – Like a stump [with nothing]? Rather, come and see how much more the Holy One blessed be He appreciates entering the Land of Israel than leaving it. Below, it is written: “Their horses…their mules…their camels” (Ezra 2: 66–67), but here it is written: “A man…went” – like a stump. As opposed to below [the exiled Judeans returning to the land, as described in Ezra], because they were departing from the Land to outside the Land, the verse did not attribute their property to them. “A man…went” – like a stump.
“To reside in the fields of Moav” – Rabbi Levi said: Every place⁵¹It does not mean every place literally; depending on the context, there are places where field means city, e.g. when the field is mentioned as a place of residence. you find field, it is a city; [where you find] city, it is a province; province, it is a country. Field, it is a city – as it is stated: “Go to Anatot, to your fields” (I Kings 2:26). City – it is a province, as it is stated: “Pass in the midst of the city, in the midst of Jerusalem”⁵²The word medina can refer to either a large city or a province. (Ezekiel 9:4). Province – it is a country, as it is stated: “One hundred and twenty-seven provinces” (Esther 1:1).
“He, his wife, and his two sons” – He was primary; his wife, secondary to him; and his sons, secondary to them.
