נֽוֹאֲלוּ֙ שָׂ֣רֵי צֹ֔עַן נִשְּׁא֖וּ שָׂ֣רֵי נֹ֑ף הִתְע֥וּ אֶת־מִצְרַ֖יִם פִּנַּ֥ת שְׁבָטֶֽיהָ׃
Estultos tornaram-se os príncipes de Zoã, enganados estão os príncipes de Mênfis; fizeram errar o Egito, os que são a pedra de esquina das suas tribos.
Taanit
it is written here, 'and they will become foolish,' and it is written there (Numbers 12:11), 'that we have become foolish and that we have sinned'; and if you want, I will say from here: 'The princes of Tsoan have become foolish, [etc.] and they have misled Egypt' (Isaiah 19:13).
Makkot
"Anyone who loves to learn in public, that is his reward." And this is [similar to] what Rabbi Yose bar Rabbi Hanina said: "What is that which is written, 'The sword on the sorcerers (badim), that they be made fools of!' (Jeremiah 50:36)? A sword on the necks of those who hate the students of the Sages who sit and busy themselves with Torah alone (bad ve-bad). And that is not all, for they are foolish! It is written here 'that they be made fools of' (Jeremiah 50:36), and it is written there 'that we have done foolishly' (Numbers 12:11). And that is not all, for they are sinners! As it says, 'and that we have sinned' (Numbers 12:11)." And if you want to say from [that they are sinners] from here: "Princes of Zoan have become fools" (Isaiah 19:13).
Berakhot
If thou wilt I can quote the following: "The princes of Zoan are become fools" (Is. xix. 13).
