פירוש על שמואל א 11:2

Each right eye. Explain it literally.¹As a symbol of everlasting defeat. But the Midrash Aggadah [explains it figuratively, that he said,] "Bring me your Torah scroll which was given by the right hand [of God],²See Devarim 33:2. and I will burn it, because He wrote in it, "Neither an Ammonite nor a Moavite may enter [into Adonoy's community]."³Devarim 23:4. Therefore, Nochosh said that he cannot accept any form of peace treaty with the Bnei Yisroel when the Torah specifically forbids to seek peace with Ammon. In Devarim 23:7 the Torah stated with regard to Ammon and Moav, “You shall not seek their peace or welfare, all your days, forever.” Nochosh therefore wanted to burn the Torah.

A sign of shame. An insult.
