Musar su Isaia 1:20

Similarly, before Israel received the gift of the Holy Land, they underwent a period of tiresome wandering in the desert dependent on the largess of G–d on a daily basis. The desert experience was a sample of the sanctity of ארץ ישראל. Our sages said that the Tabernacle itself was also called מקדש, Temple (Eruvin 2a). This may account for the fact that whenever the Israelites sinned, punishment followed at once. In line with this is the statement that no one was allowed to spend the night in Jerusalem while in a state of sin, i.e. his sin had to be atoned for before nightfall through immediate יסורים, afflictions of some kind (Bamidbar Rabbah 21). Isaiah 1,21, says of Jerusalem: "צדק ילין בה," righteousness would spend the night there. What is meant is "justice and righteousness" should prevail there, but G–d collected His debt only in installments, a little at a time in order to fulfill His promise of רק אתכם ידעתי מכל משפחות האדמה, על כן אפקוד עליכם על כל עונותיכם, "Only you I have singled out from all the families of the earth; therefore I will call you to account for all your iniquities" (Amos 3,2).
