וְנָתַתָּ֨ לְעַבְדְּךָ֜ לֵ֤ב שֹׁמֵ֙עַ֙ לִשְׁפֹּ֣ט אֶֽת־עַמְּךָ֔ לְהָבִ֖ין בֵּֽין־ט֣וֹב לְרָ֑ע כִּ֣י מִ֤י יוּכַל֙ לִשְׁפֹּ֔ט אֶת־עַמְּךָ֥ הַכָּבֵ֖ד הַזֶּֽה׃
所以求你賜給你僕人一顆善於聽斷的心，能審判你的子民，能分辨善惡；不然，誰能審判你這眾多的子民呢？»
Rashi
This great people of Yours. Since they are many, they have many dealings, and they come to litigate and I have no time to deliberate over their arguments. Another interpretation of, “for who is able to judge this great people of Yours,” their legal decisions are very difficult [for me to make]. If a lawsuit comes before me between two non-Jews, and I take from one and give to the other unjustly, I will not be punished. But [if a lawsuit comes before me] between Jews [and I take from one and give to the other unjustly], I will be punished for it with capital punishment,19That is why Shlomo refers to the Bnei Yisroel as a “weighty [=כבד] nation.” as it is stated, “And He takes the lives of those that steal from them.”20Mishlei 22:23.
