פִּֽי־כְ֭סִיל מְחִתָּה־ל֑וֹ וּ֝שְׂפָתָ֗יו מוֹקֵ֥שׁ נַפְשֽׁוֹ׃
Ang bibig ng hangal ay kanyang ikapapahamak, at ang kanyang mga labi ay bitag ng kanyang kaluluwa.
Rabbeinu Bahya
A Midrashic approach to the words: “are you going to gouge out the eyes of those men, we will not go up!” It is significant that the Torah did not quote them as saying: “we will not go,” or; “we will not come,” but wrote “we will not ascend, go up.” Their mouth betrayed them as having refused to ascend. They died by descending into the earth and into purgatory. They had prepared the way they were going to die with their own mouths.
