Midrash su Isaia 1:23

R’ Elazar said: the whole Torah hangs on judgment. That is why the Holy One gave the laws of justice after the Ten Commandments - because people cross the line of justice, are punished and this teaches the whole world. Sodom was not overturned until it crossed the line of justice, as it says “…pride, abundance of bread, and careless ease…“ (Ezekiel 16:49) Even Jerusalem was not exiled until she crossed the line of justice, as it says “…the orphan they do not judge, and the quarrel of the widow does not come to them.” (Isaiah 1:23) And why did the Holy One give the crown to Yehudah? He is not the sole mighty one from among his brothers, are not Shimon, Levi and the others mighty as well? Rather, it was because he gave true judgment to Tamar, therefore he was made judge of the world. This is like a judge before whom an orphan’s judgment comes and he finds in her favor. So too Yehudah – Tamar’s judgment that she should be burned came before him, and he found in her merit because he found merit in her. How? Yitzchak and Yaakov were sitting there, and all his brothers were covering for him. Yehudah acknowledged Gd (HaMakom) and spoke the truth of the matter, saying “She is more in the right than I…” (Bereshit 38:26) and the Holy One made him prince. So Ben Zoma used to say and explain: if you were ashamed in this world, you will not be ashamed of the Holy One, who is a consuming fire, in the coming world. Why? Because the shame of this world is nothing other than the shame of one’s standing in the coming world, as it says “For this let every pious man pray to You…” (Tehillim 32:6)
